Abstract

PURPOSE:To easily manage information recorded on an optical disk medium by disposing a magnetic recording part capable of rewriting on a protecting cartridge and reproducing/recording the information of a magnetic disk recording medium at the time of loading and taking out the optical disk medium. CONSTITUTION:The optical disk medium 31 incorporated protecting cartridge 30 is inserted from the cartridge inserting port 5a of a front mask 5 and pushed to an interior in an X1 direction, and then, a microswitch 11 is touched to turn on the switch. Accordingly, a cartridge feeding means is operated to feed the protecting cartridge 30 to the X1 direction at a constant speed, the magnetic head 10 scan the magnetic recording medium longitudinally to reproduce recorded information. At the time of taking out the optical disk medium 31, the cartridge feeding means operates reversely to record the information on the magnetic recording medium when the protecting cartridge 30 is fed to an X2 direction. Thereby, a cost is lowered and a system is simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to write-once optical disc devices (2), and more particularly to recording/reproduction using an optical disc medium built into a protective cartridge.

(Prior Art) Conventionally, when handling a plurality of information recording media, in order to manage the contents recorded on each recording medium, it is necessary to frequently rewrite an index that summarizes the recorded contents. However, since write-once optical disk devices cannot be rewritten, magnetic disk devices have been used in conjunction with optical disk devices to manage the recorded contents of optical disks.

(Problems to be Solved by the Invention) The above-described conventional optical disk device has the disadvantage that when a magnetic disk device is used in combination with the optical disk device, the cost of the information processing system becomes relatively high and the system becomes complicated.

An object of the present invention is to provide an optical disk device that performs recording and reproduction using an optical disk medium built in a protective car (IJ), which includes a cartridge feeding means for internally loading and unloading a protective cartridge, The above-mentioned drawbacks are eliminated by mounting the magnetic head at a position where the purulent cartridge contacts the surface of the magnetic recording medium when the protective cartridge is sent by means of the present invention, and the system is constructed to reduce costs and simplify the system. The purpose of the present invention is to provide an optical disc device.

(Means for Solving the Problems) An optical disk device according to the present invention includes a cartridge feeding means and a magnetic head, and performs recording/reproduction on an optical disk medium built in a protective cartridge.

The cartridge feeding means is for loading or unloading the protective cartridge.

The magnetic head is for managing recorded contents at a position where it comes into contact with the surface of the magnetic recording medium on which the protective cartridge is placed when the protective cartridge is fed by the cartridge feeding means.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a longitudinal sectional view showing an embodiment of an optical disc device according to the present invention.

In FIG. 1, 1 is a base plate, 2 is an optical head, 3 is a spindle motor, 4 is a pace chassis, 5 is a front mask, 5a is a cartridge insertion slot, 6 is a dog cover, 7 is a circuit board, 8 is a cartridge guide, 9 is a back plate, 10 is a magnetic head, 11 is a micro switch, 12.13 is a shutter opener, 30
is a protective cartridge.

The optical disk device shown in FIG. 1 has an exterior that includes a front mask 5, a top cover 6, a pace chassis 4, a back plate 9, a spindle motor 3 for rotating an optical disk medium 31, and a spindle motor 3 for recording information. /An optical head 2 for reproducing, a cartridge guide 8 that serves as a guide when loading the protective cartridge 30 inside and holds the protective cartridge 30 during recording/reproducing, and recording/reproducing on a magnetic recording medium. It consists of a magnetic head 10 for performing
0 into the optical disc medium 31 and positions it in a state where recording/reproduction on the optical disc medium 31 can be performed.

FIG. 2 is a perspective view of the optical disc medium and the protective cartridge.

In FIG. 2, 30 is a protective cartridge, 30a is a shutter, 30b is a magnetic recording medium, 30C is a front part of the cartridge, 31 is an optical disk medium, and 31a is an optical disk center hole.

The protective cartridge 30 contains an optical disc medium 31,
The recording medium 30b includes a magnetic recording medium 30a and a magnetic recording medium 30b. The shutter 30a slides toward Kl- in two directions, and the second
As shown in Figure 2, recording/reproduction is performed on the optical disc medium 31 in a state where the optical disc medium 31 is pushed in two directions and exposed outside the protective cartridge 30.

A protective cartridge 30 with a built-in optical disk medium 31
When inserting the cartridge into the front mask 5 with the front portion 30C of the cartridge inserted first from the front mask 5a and pushing it inward in the X1 direction, the protective cartridge 30 touches the microswitch 11 and turns on.

As a result, the cartridge feeding means is activated, and the protective cartridge 30 is fed at a constant speed in the X1 direction. At this time,
Since the magnetic head 10 is on the orbit of the magnetic recording medium 30b on the protective cartridge 30, the magnetic head 10 scans the magnetic recording medium 30b in the longitudinal direction.

In this way, information recorded on the magnetic recording medium 30b on the protective cartridge 30 can be reproduced when the optical disc medium is loaded.

When the protective cartridge 30 is sent to the innermost part of the cartridge guide 8, the cartridge guide 8 is lowered by the cartridge feeding means, and the protective cartridge 30 is moved to position A.
is positioned.

At this time, the optical disc medium 31 is placed on the turntable 3a of the spindle motor 3, and the optical disc medium 31 is placed on the turntable 3a of the spindle motor 3.
Recording/playback is now possible.

When taking out the optical disc medium 31, the cartridge feeding means operates in the opposite manner to the above, and the protective cartridge 30
Information is recorded on the magnetic recording medium 30b when it is sent in two directions.

Since the direction in which the magnetic head 10 scans the magnetic recording medium 30b is opposite during loading and unloading, information is recorded in the reverse order from the end to the beginning of a continuous series of information.

(Effects of the Invention) As explained above, the present invention provides a rewritable magnetic recording section in the protective cartridge, and reproduces/records information on the magnetic recording medium when loading/unloading the optical disk medium, thereby achieving a simple method. This has the effect that the information recorded on the optical disc medium can be easily managed.
