Abstract

PURPOSE:To obtain a cartridge capable of recording and reproducing and also loading and unloading a recording disk by providing an insertion member of magnetic substance capable of inserting into a hole of the recording disk and mounting the disk between a motor provided with a magnet on its part to be engaged with the disk and the insertion member. CONSTITUTION:When the recording disk 2 without having the magnetic substance in a center part but having the hole 2a is set to a back lid 1a of the cartridge and a front lid 1a is closed, a conical part of the insertion member 3 is inserted into the hole 2a of the disk. The cartridge 1 is installed in a recording and reproducing device provided with the magnet 9 on a part of the motor 8 for engaging with the recording disk. A center shaft 10 of the motor 8 is inserted into the hole of the member 3, and the disk 2 is securely clamped between the conical surface of the member 3 and the motor 8 by the magnet 9 in its attracting force. The disk 2 is rotated by the motor 8, and a bit of information can be recorded and reproduced. These operations are reversible, and the loading and unloading of the disk can simply be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a recording disc storage container for storing a recording disc therein.In particular, the present invention relates to a recording disc storage container that stores a recording disc therein. The present invention relates to a structure in which a magnetic insertion member is inserted into a hole by being housed in a cartridge.

2. Description of the Related Art In recent years, systems for recording and reproducing information on a recording disk called an optical disk using a laser beam have been attracting attention.

In general, this recording disk called an optical disk does not use a cartridge as shown in 2 in Figure 2 and is used without a magnetic material attached to the center, or it is used with a cartridge 1' as shown in 2' in Figure 3. There are discs that are stored in a disc and are used with a magnetic plate 6 attached to the center, but these two types of recording disks can only be used with dedicated recording and reproducing devices, so they can only be used in one recording and reproducing device. It is desired to be able to record and reproduce these two types of recording disks.

Problems to be Solved by the Invention However, for example, when a magnetic material is installed in the center of a recording disk housed in a cartridge, a magnet is attached to the center of the motor in order to engage the recording disk and attract it to a rotating motor. A recording/playback device installed with a car)! J
- In order to use a recording disk that is not stored in a storage box and has no magnetic material attached to the center of the recording disk, a magnetic material is inserted into the center of the recording disk so that it is attracted to a magnet installed in the motor. Even if you try to use it by storing it between the cartridge and the storage disc, the recording disc will not be attracted to the motor unless there is a magnetic material in the center of the recording disc, so the recording disc will not be able to rotate, and the information will be lost. The problem was that it was not possible to record and play back.

In view of this, the present invention has been developed to provide a recording disk that has a hole in the center and does not have a magnetic material installed therein, instead of a recording disk that has a magnetic material in the center of the recording disk and is stored in a cartridge. An object of the present invention is to provide a recording disc storage container in which an insertion member is inserted and engaged with a recording disc and clamped to a rotating motor by storing the container in a cartridge that enables recording and reproduction by a reproducing device. It is something.

Means for Solving the Problems The present invention has a magnetic insertion member that can be inserted into a hole in a recording disk, engages with the recording disk to rotate it, and has a magnet attached to the engaging portion. The recording disc is clamped between the motor in which the disc is installed and the insertion member.

Effect of the present invention With the above-described configuration, when a recording disk having no magnetic material and a hole in the center is housed in a cartridge, an insertion member capable of clamping the recording disk to a motor is attached to the recording disk. It is designed so that it can be inserted into the center.

Embodiment FIG. 1 shows a schematic configuration diagram of a recording disk storage container in an embodiment of the present invention.

In FIG. 1, 1aij is the cartridge back cover, 1b is the cartridge front cover, and has an opening 1C, a hole 1e, and a protrusion 1d.
is provided. 2 is a recording disk with a hole 2a in the center. Reference numeral 3 denotes an insertion member, which is made of a magnetic material and has a partially conical shape so that it can be inserted into the hole 2a of the recording disk 2.
A through hole is provided in the direction of its central axis.

Reference numeral 4 denotes a support base, which engages with a hole drilled in the axial direction of the insertion member 3 and supports one end of the shaft 8 on which the insertion member 3 is slidably attached in the axial direction, as shown in FIG. It is rotatably supported. Reference numeral 5 is provided at two angles so that the cartridge back cover 1a and the cartridge front cover 1b can be rotated around the amplifier/I 15.

The operation of the recording disc storage container of this embodiment constructed as described above will be explained below.

As shown in FIG. 1, a recording disk 2 having no magnetic material and a hole 2IL in the center as shown in FIG. 2 is installed in the cartridge back cover 1&.

Next, when the cartridge front cover 1b is rotated in the x1 direction about L/6 (amplifier), the insertion member 3 is inserted into the hole 2a of the recording disk 2. Cartridge back cover 1a and car) When the IJudge front cover 1b is closed and fixed (the fixing mechanism is not shown), it becomes as shown in Fig. 4. Insertion member 3
The conical part is inserted into the hole 2a of the recording disk 2.

When this cartridge 1 is installed in a recording/reproducing apparatus in which a magnet 9 is installed at the engagement part of the motor 8 with the recording disk as shown in FIG. A certain motor center shaft 9 is inserted into the hole of the insertion member 3, and the recording disk 2 is firmly clamped between the conical surface of the insertion member and the motor 8 by the attraction force received from the magnet 9 applied to the insertion member 3. Ru. As a result, the recording disk 2 is rotated by the rotation of the motor 8, and information can be recorded and reproduced by a recording disk recording/reproducing mechanism (not shown).

The operations described above are reversible. Therefore, the recording disk can be easily attached and detached.

FIG. 6 is a sectional view of a recording disc storage container showing a second embodiment of the present invention. In the figure, 1a is a cartridge back cover, 1b is a cartridge front cover, 2 is a recording disc, and 3 is an insertion member. , 4 is a support member, 7 is a shaft, 8 is a motor, 9 is a magnet,
1o is the central axis of the motor, and the structure described above is similar to that shown in FIG. 4. The difference from the configuration shown in FIG. 4 is that a spring 11 is installed on the mounting member 3 so as to generate a biasing force in the Y direction.

This action is exactly the same as in the first embodiment, but when the recording disk 2 is housed in the cartridge and is not clamped to the motor, the recording disk is placed between the convex portion 1d and the mounting member 3, and the motor 8 Spring 11 has a weak biasing force even though it is securely attached to the
By being lightly clamped by the disc, it is possible to prevent the recording disc from rattling due to external vibrations.

As described in detail, according to the present invention, a recording disk having no magnetic material in the center and having a hole can be attached to a motor when the recording disk is housed in the cartridge according to the present invention. A suitable insertion member can be inserted into the center of the recording disk, thereby allowing the cartridge to be inserted into the center of the recording disk. It is now possible to record and play back information on a recording disk that is stored in a cartridge and has a magnetic material attached to its center, and that the recording disk can be easily attached and removed from the cartridge. Its practical effects are great.
