Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording device, and more particularly to an information recording device using a magneto-optical disk and a floppy disk.

[0002]

2. Description of the Related Art Removable rewritable memory devices used in the present computer environment include magneto-optical disks and floppy disks. These are published in Japan Applied Magnetics Society, Vol. 18 No. 6 (1994)
As discussed on pages 973-980,
They are used together making the most of their features. At present, devices for magneto-optical disks and floppy disks are used for these two users, instead of an integrated drive device.

[0003]

In recent years, with the increase in the amount of information handled by computers, various types of information recording devices such as hard disks and CD-ROMs have come to be used in addition to the above-mentioned discs. These disks are driven using their respective independent devices. Therefore, if you try to systematically install these device groups in one place,
A big space was needed. An object of the present invention is to provide an information recording apparatus capable of integrally recording / reproducing both a magneto-optical disk and a floppy disk in order to save space.

[0004]

SUMMARY OF THE INVENTION The above-mentioned object is to devise a magnetic head as described below and to provide a magnetic head and an optical head for recording on a magneto-optical disk in one information recording device, and a floppy disk. It is achieved by including a magnetic head for recording.

Both a magnetic head for a magneto-optical disk and a magnetic head for a floppy disk are mounted on one head support.

A magnetic head for recording on the floppy disk is added to the optical head arranged opposite to the magnetic head with the magneto-optical disk or the floppy disk sandwiched therebetween.

[0007]

EXAMPLES Examples of the present invention will be described below with reference to schematic diagrams.

FIG. 1 is a schematic view showing an example of a magnetic head portion of an information recording apparatus according to the present invention. Both a magnetic head for a magneto-optical disk and a magnetic head for a floppy disk are mounted on a head support made of a gimbal spring.

FIG. 2 shows a sectional view of this magnetic head portion.

As an example of the shape of the head support (a),
(B) Two types are shown, but the shape is not limited to these. During operation of the floppy disk, the floppy disk head contacts the disk surface as usual. At this time, the magnetic head for the magneto-optical disk is preferably floating above the disk surface, but it is also possible to make contact with the disk surface. Further, even during operation of the magneto-optical disk, it is preferable that the magnetic head for the magneto-optical disk operates in a non-contact state with the disk surface on the recording film surface side, but it is also possible to operate in a contact state. At this time, the floppy disk head may float or be in contact with the disk surface on the recording film surface side.

FIG. 3 shows a head for a floppy disk which is added to an optical head which is arranged so as to face the above magnetic head with a disk-shaped record carrier interposed therebetween. (A) shows the operation of the magneto-optical disk, and (b) shows the operation of the floppy disk. Since the floppy disk records on both upper and lower surfaces, it is sandwiched between the upper and lower magnetic heads during operation as shown in FIG. The lower surface recording magnetic head added to the optical head has a mechanism for moving up and down, and moves to the upper portion when the floppy disk operates and moves to the lower portion when the magneto-optical disk operates. The floppy disk head moved to the lower part is not in contact with the substrate of the magneto-optical disk. As the magneto-optical disk used in the present invention, a single plate disk is preferable as shown in FIG. The magneto-optical recording method is preferably a magnetic field modulation method or an optical pulse magnetic field modulation method, but an optical modulation method is also possible.

The information recording apparatus of the present invention is provided with the magnetic head and the optical head for recording on the magneto-optical disk and the magnetic head for recording on the floppy disk by the device described in the above embodiment. Therefore, this device 1
Record both magneto-optical disk and floppy disk
Playback is now possible. Further, in the information recording apparatus of the present invention, the number of disk insertion ports can be one for both the magneto-optical disk and the floppy disk.

[0013]

As described above, in the present invention, the magnetic head is devised so that the magnetic head for recording on the magneto-optical disk and the optical head for recording on the magneto-optical disk and the recording on the floppy disk can be performed in one information recording apparatus. Since it was equipped with a magnetic head, it was possible to record and reproduce both magneto-optical disks and floppy disks with this single device. This is extremely effective for downsizing the information recording device and simplifying the information recording system.
