Abstract

(57) [Summary] [Purpose] To obtain a data backup device that can quickly obtain index information without managing backup data. [Structure] A small-scale recording medium for recording index information is provided in the recording medium body.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a data backup device such as a computer.

[0002]

[Prior Art]

 5 to 7 are views showing a conventional data backup device, FIG. 5 is a front view showing the whole, FIG. 6 is a side view of a magnetic tape, and FIG. 6 is a front view of a wrist. In the figure, 1 is a computer, 2 is a magnetic tape device connected to the computer 1, 3 is a printer device connected to the computer 1, 4 is a magnetic tape, 5 is a header portion on the magnetic tape 4, and 6 is a data portion. , 7 are lists output from the printer device 3.

Next, the operation will be described. In the data backup device, the data of the computer 1 is recorded on the magnetic tape 4 by using the magnetic tape device 2. At that time, index information such as a file name is written in the header portion 5 on the magnetic tape 4, and the data to be backed up is recorded in the data portion 6. When the backup of the data is completed, the printer device 3 outputs the index information regarding the data backed up on the magnetic tape 4 to the list 7 according to an instruction from the computer 1.

[0004]

[Problems to be solved by the device]

 Since the conventional data backup device is configured as described above, since the medium 4 in which the data is recorded and the list 7 indicating the contents are different, if the list 7 is erased, the contents in the medium 4 are deleted. There is the problem that the header part 5 of the medium has to be decrypted in order to know Further, when a plurality of data are recorded on one medium, the header portion 5 in the medium must be decoded from the beginning to the end, which is very troublesome.

In order to solve the above problems, the present invention provides a data backup device in which a part for recording only index information of contents in a medium is provided in a medium body and management of backup information by a list is unnecessary. The purpose is to get.

[0006]

[Means for Solving the Problems]

 In the data backup device according to the present invention, a small-scale recording medium is provided in the main body of the data recording medium separately from the portion for recording data. Further, the device for recording data on this medium has a portion for reading / writing information on the above-mentioned recording medium, in addition to the portion for reading / writing data on the magnetic tape.

[0007]

[Action]

 The data backup device according to the present invention records index information such as the name of the data on the magnetic card of the medium body at the same time as recording the data on the magnetic tape.

[0008]

【Example】

 Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. 1 is a front view of a magnetic tape device according to a first embodiment of the present invention, and FIG. 2 is a side view of the magnetic tape device. In the figure, 2 is a magnetic tape device, 8 is a head for reading and writing data on a magnetic tape, 9 is a head for reading and writing data on a magnetic card attached to the magnetic tape 9, 4 is a magnetic tape, and 11 is a magnetic tape. It is a magnetic card attached to 10. In the data backup according to the first embodiment, writing and reading of data on the magnetic tape 4 is performed by the magnetic head 8 as in the conventional case. However, the index information regarding the content of the recorded data is compared with the conventional backup. Similarly, the data is recorded on the header portion, and at the same time, it is written on the magnetic card 10 attached to the back surface of the magnetic tape 4 by the magnetic head 9.

When referring to what data is recorded on the magnetic tape 4, the magnetic head 9 reads only the index information recorded on the magnetic card 10. If the list 7 is required, the information read by the magnetic card 10 is output from the printer 3.

Example 2. Although the magnetic card 12 is attached to the back surface of the magnetic tape 4 in the first embodiment, a storage element 11 such as a static RAM may be attached instead of the magnetic card as shown in FIG. .. In FIGS. 3 and 4 showing the second embodiment, 11 is a storage element such as a static RAM, 12 is a spindle of a magnetic tape device, and 13 is a device for reading and writing information from and into 12. In this example, when the magnetic tape 4 is attached to the magnetic tape device 2, the storage element 11 is attached to the read / write device 13 attached to the spindle 12, and the index information of the data recorded on the magnetic tape can be read and written.

[0011]

[Effect of the device]

 As described above, according to the present invention, it is not necessary to manage the backup data by the list, and if the contents of the backup data are to be known, it is not necessary to read all the header parts of the medium, and the backup data can be easily It has the effect of confirming the contents.
