Description

OPTICAL INFORMATION STORAGE MEDIUM AND METHOD OF RECORDING DATA THEREON
Technical Field
The present invention relates to an optical information storage medium on which information about the state of a disk is newly recorded every time recording of user data is completed, and a method of recording data on the optical information storage medium.
Background Art
General information storage media are widely used as information recording media of optical pickup apparatuses for recording/reproducing information in a non-contact way. Optical disks, which are information storage media, are classified as compact disks (CDs) or digital versatile disks (DVDs) according to their information storage capacity. Examples of recordable optical disks are 650MB CD-R, CD-RW, 4.7GB DVD/RW, DVD-RAM, and the like. Furthermore, HD-DVDs having a recording capacity of 20GB or greater are under development. In particular, write-once information storage media, among recordable optical information storage media, are usually used as backup optical information storage media for PCs or as audio/video (A/V) optical information storage media. User data is recorded on write-once information storage media in order of physical addresses, and data is no longer recorded on a physical address at which data has already been recorded. Accordingly, when recording is stopped and then resumed, data will be recorded on an area next to the area containing the most recently recorded data. As described above, write-once information storage media requires a new physical data structure having characteristics different from those of rewritable optical information storage media.
Disclosure of the Invention One aspect of the present invention provides an optical information storage medium in which data about a recent disk state is newly recorded upon every data recording so that an area in which new data is to be recorded can be rapidly accessed by a pickup using the recorded disk state data, and a method of recording data on the optical information storage medium.
According to an aspect of the present invention, there is provided an optical information storage medium in which a reproduction-only area and a recordable area are included in an area other than a user data area, and new data about a disk state is recorded in the recordable area every time recording of user data is stopped.
According to one aspect of the invention, the data about a disk state includes at least one datum selected from the group consisting of the address of an area containing newly recorded optimum power control (OPC) data, the address of an area containing the most recently recorded drive data, the address of an area containing the most recently recorded user data, and data representing whether additional recording after recording of user data is possible.
According to one aspect of the invention, the data about a disk state is recorded in the recordable area of a lead-in area.
According to one aspect of the invention, the data about a disk state is updated, and new data about a disk state is recorded in an area next to the area containing the most recently recorded disk state data.
According to another aspect of the present invention, there is provided a method of recording data on an optical information storage medium in which a reproduction-only area and a recordable area are included in the area other than a user data area. This method includes recording user data, and recording new data about a disk state in the recordable area every time recording of user data is stopped. Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention. Brief Description of the Drawings
FIG. 1 schematically shows the data structure of an optical information storage medium according to one aspect of the present invention; FIG. 2A shows disk state data recorded on an optical information storage medium according to one aspect of the present invention; and
FIG. 2B is a view for explaining a method of recording disk state data on an optical information storage medium according to one aspect of the present invention.
Best mode for carrying out the Invention
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.
Referring to FIG. 1 , an optical information storage medium according to one aspect of the present invention includes a reproduction-only area 10 and a recordable area 15 in the area other than a user data area. For example, the area other than a user data area can be a lead-in area located on the inner side of the user data area in the radial direction of a disk. The reproduction-only area 10 stores disk-related data, such as, the type, version number, size of a disk, the number of layers, and the like. This data is already recorded on a substrate in the form of pits or groove wobbles upon the manufacture of a disk and accordingly is only reproduced.
The recordable area 15 includes an optimum power control (OPC) zone 15-a for recording data used for optimal power control, a disk zone 5-b for recording data about disk states, and a drive zone 15-c for recording drive-related data. Examples of the disk state data include the address of an area containing new OPC data, the address of an area where the last drive information has been recorded, the address of an area where the last user data has been recorded, and data representing whether additional recording is possible, or impossible, after user data is recorded. According to one aspect of the present invention, at least one of these disk state data is recorded on the disk zone 15-b. The OPC zone 15-a records data about recording and/or reproduction power, which is used to record and/or reproduce user data, every time the user data is stopped. The recording and/or reproduction power can be optimally controlled based on the data about recording and/or reproduction power. Every time recording is performed, new data about power, which is used during recording, is recorded. In write-once optical information storage media, every time new recording is performed, OPC data is recorded on a new area where data is not recorded. Accordingly, when recording is completed and then new recording is executed, an area on which new OPC data is to be recorded must be searched for. According to one aspect of the present invention, the address of the area containing the newly recorded OPC data is recorded in a predetermined area so as to enable a rapid access. That is to say, the address of an area containing the most recently recorded OPC data is recorded on the disk zone 15-b. Upon new data recording, new OPC data can be rapidly accessed by only reproducing the address of the area containing the most recently recorded OPC data without a need to reproduce all of the OPC areas.
The drive zone 15-c records drive-related data, such as, data about a drive manufacturer or the serial number of a drive. Every time recording is executed, data about a drive that performs the recording is newly recorded. Hence, according to one aspect of the present invention, the address of an area containing the most recently recorded drive data is recorded as the disk state data. Accordingly, when new drive data is recorded, a position where the new drive data is to be recorded can be easily searched for by reproducing the recorded address of the area containing the most recently recorded drive data. When recording of user data is interrupted and new data is recorded, a pickup must access an area where the new data is to be recorded. To achieve a rapid access, according to one aspect of the present invention, the address of the area containing the most recently recorded user data is recorded in a predetermined area.
As described above, if recent disk-related data is not provided, the OPC zone 15-a, the drive zone 15-c, or the user data area is entirely read upon recording of user data. Thus, significantly much time is taken to access an area in which the user data is to be recorded.
According to one aspect of the present invention, after recording of user data is completed, data representing whether additional data can be recorded on an area next to the area containing the finally recorded user data is recorded. In order to prevent further recording, data representing the impossibility of additional recording after completion of recording is recorded. On the other hand, if additional recording can be performed, data representing the possibility of additional recording after the completion of recording is recorded. Every time data recording is completed, such disk state data is recorded in a predetermined area, for example, the disk zone 15-b, of the recordable area 15 included in a lead-in area. When new data is recorded, a pickup can accurately and rapidly access an area where the new data is to be recorded, using the recorded disk state data. One aspect of the present invention is effectively applicable to write-once optical information storage media.
When disk state data are recorded, each datum can be recorded in at least one byte of the disk zone 15-b. Examples of bytes, which record disk state data, include the bytes of a physical cluster, the bytes of an ECC block, or the bytes of a sector. Referring to FIG. 2A, the address of an area containing newly-recorded OPC data is recorded in an a-th byte, the address of an area containing the most recently recorded drive data is recorded in a b-th byte, and the address of an area containing the most recently recorded user data is recorded in a c-th byte. Also, data about whether additional recording is possible, or impossible, after the completion of recording can be recorded in a d-th byte. Each of these disk state data may be recorded in one byte as shown in FIG. 2A, or may be recorded in two or more bytes. As shown in FIG. 2B, a byte is comprised of seventh through zeroth bits, i.e., b7 through bO. If the address of an area containing newly recorded OPC data is recorded in one byte, it can be represented as a combination of bits. For example, the address can be recorded in the form of 0001 b, 0010b, or 0011 b using the seventh through fourth bits b7 through b4.
Likewise, the address of an area containing the finally recorded drive data and the address of an area containing the finally recorded user data can be recorded in different bytes. For example, in the recording of the data about the possibility or impossibility of additional recording, 00000000b can be recorded to represent the possibility of additional recording, and 00000001 b can be recorded to represent the impossibility of additional recording.
The disk state data according to one aspect of the present invention is updated every time user data is recorded. According to one aspect of the present invention, the disk state data is updated in such a way that new disk state data is recorded in an area having no recorded data. In other words, disk state data are recorded in different areas so as to prevent duplicate recording of data in the same area. According to another aspect of the present invention, new disk state data is recorded in an area next to the area containing the most recently recorded data. Each of the disk zone 15-b and the drive zone 15-c is comprised of 1000 or more physical clusters.
In an optical information storage medium according to one aspect of the present invention, a reproduction-only area and a recordable area are included in the area other (e.g., a lead-in area) than a user data area. In a method of recording data on the optical information storage medium according to one aspect of the present invention, recent data about disk states is recorded in the recordable area. User data is first recorded, and every time the user data is completely recorded, disk state data is newly recorded in the recordable area. If new disk state data is recorded, it is recorded in an area next to the area containing the most recently recorded disk state data. Examples of the disk state data include the address of an area containing newly recorded OPC data, the address of an area containing finally recorded drive data, the address of an area containing finally recorded user data, and data representing whether additional recording after recording of user data is possible. According to one aspect of the present invention, at least one of these is recorded as the disk state data. In addition, the address of an area, in which new control data is recorded every time user data recording is completed, is recorded as the disk state data.
Industrial Applicability
As described above, in an optical information storage medium according to one aspect of the present invention and a method of recording data on the optical information storage medium, every time user data recording is completed, recent data about a disk state is recorded. Thus, when new data is recorded, a pickup can accurately and rapidly access an area where the new data is to be recorded. Also, because the user data can be recorded using the recent data about a disk state, recording and/or reproduction performance can be improved. Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
