[0075] Further, the locking mechanism 29 is in the initial state, by switching member 103 is rotated in the arrow c ₁ direction, the transmission control member 68 is restricted to move in the arrow b ₂ direction . Therefore, the lock mechanism 29
In this case, the operation force by operating the rotation operation lever 67 of the recording operation mechanism 28 is not transmitted to the head operation member 70.

In the optical disk device 1 configured as described above, the detection operation of detecting the disk cartridges 3 and 4 mounted on the cartridge mounting portion by the cartridge identification mechanism 27, and the operation of the head lifting mechanism 26 by the recording operation mechanism 28 The lifting operation and the operation by which the lock mechanism 29 disables the operation of the head lifting mechanism 26 by the recording operation mechanism 28 will be described with reference to the drawings.

First, when the pit disk cartridge 4 is inserted and mounted on the cartridge mounting portion, the optical disk device 1 identifies the identification portion 15 of the pit disk cartridge 4 mounted on the cartridge mounting portion as shown in FIG. within, by detecting piece 63 of the detecting member 60 of the cartridge identification mechanism 27 is inserted, the detection piece 63 of the detecting member 60 is not pushed by the pits disk cartridge 4, the detection member 60 is rotating in the arrow c ₂ direction Not moved. The cartridge identifying mechanism 27 identifies that the disk cartridge mounted on the cartridge mounting unit is not recordable because the detecting member 60 is not rotated.

Then, the optical disk device 1 is operated when the pit disk cartridge 4 to be unrecordable is mounted on the cartridge mounting portion and when the disk cartridges 3 and 4 are not mounted on the cartridge mounting portion in the initial state. As shown in FIG. 7, when the switching member 103 of the lock mechanism 29 is rotated in the direction of the arrow c ₁ , the regulating pin 124 of the switching member 103 is engaged with the regulating piece 80 of the transmission control member 68. .

[0079] Thus, the recording operation mechanism 28, as shown in FIG. 7, the transmission control member 68 is impossible to move in the arrow b ₂ direction by rotating operating the rotation operation lever 67 Accordingly, it is impossible to operate the head elevating mechanism 26 via the transmission control member 68.

Further, the optical disk device 1 is used when the pit disk cartridge 4 which is not recordable is mounted in the cartridge mounting portion, and when the disk cartridges 3 and 4 are not mounted in the cartridge mounting portion in the initial state. As shown in FIG. 7, since the head operation member 70 is at a position where the head operation member 70 is not engaged with the transmission control member 68 of the recording operation mechanism 28, the transmission control member 68 performs an idle swing operation, so that the recording operation mechanism 28 Operation has been disabled.

Next, in the optical disk device 1, when the magneto-optical disk cartridge 3 is mounted on the cartridge mounting portion, as shown in FIG. by contacting the identification unit 10, the detection member 60 is rotated in Figure 8 in the arrow c ₂ direction rotation support shafts 62 as the pivot center.

[0082] cartridge identification mechanism 27, as shown in FIG. 8, detected by the member 60 is rotated in the arrow c ₂ direction, the interlocking member 61 is drawn in the arrow d ₂ direction in FIG. 7, the recording operation the head operating member 70 of the mechanism 28 rotates the guide shaft 87 in arrow in FIG. 8 c ₂ direction as the pivot center.

The recording operation mechanism 28, as shown in FIG.
A head operating member 70 is rotated in the arrow c ₂ direction, the engagement piece 96, the engagement piece 83 of the transmission control member 68
Is moved to a position where it can be engaged. That is, the recording operation mechanism 28, in a state where the head operating member 70 is rotated in the arrow c ₂ direction by the cartridge identification mechanism 27,
The head lifting mechanism 26 can be operated.

Then, after the cartridge identifying mechanism 27 identifies that the magneto-optical disk cartridge 4 mounted on the cartridge mounting portion is recordable, the recording operation mechanism 28
As shown in FIGS. 8 and 9, by rotating the rotation operation member 67 in the direction of arrow c _{2 in} FIG. 9, the transmission control member 68 is moved in the direction of arrow b _{2 in} FIG. The engagement piece 83 of the member 68 is engaged with the engagement piece 78 of the head operation member 70.
Is engaged. The recording operation mechanism 28 includes the rotation operation lever 6.
7 through, by moving the transmission control member 68 in the arrow b ₂ direction, the head operating member 70 to FIG. 9 arrow b ₂
Moved in the direction.

The recording operation mechanism 28, as shown in FIG.
By moving the head operating section 70 material arrow b ₂ direction, the slide member 44 of the head lifting mechanism 26 arrow b
Move in _two directions. Therefore, the head elevating mechanism 26
As shown in FIGS. 5 and 6, the magnetic head 36 of the magnetic head unit 23 is moved down to the recording position by lowering the magnetic head 36 with respect to the magneto-optical disk 6.

The lock mechanism 29 is, as shown in FIG.
By stopping the power supplied to the plunger 104, the attraction by the magnet 129, the metal piece 131 is moved in FIG. 10 the arrow b ₁ direction. As shown in FIG. 10, the lock mechanism 29 is configured such that the metal piece 131
By being moved in _one direction, the switching member 103 is rotated in the arrow c ₂ direction.

The lock mechanism 29 is, as shown in FIG.
Switching member 103, by being rotated in the arrow c ₂ direction, it is released rotation of the lock member 101 by the restricting portion 123, the locking member 101 is rotated in the arrow c ₂ direction. The lock mechanism 29 is such that the lock member 101 has an arrow c.
By rotating in _two directions, the locking pawl 110 is engaged with the engaging groove 95 of the head operating member 70, the head operating member 70 is impossible to move in the arrow b ₁ direction and the b ₂ directions I have.

Therefore, after the lowering operation of the magnetic head 36 by the head elevating mechanism 26 is completed, the lock mechanism 29 is in a locked state in which the moving operation of the head operating member 70 is impossible. That is, the optical disc device 1
After the magnetic head 36 is moved to the recording position with respect to the magneto-optical disk 6, it is impossible to move the magnetic head 36 to the retracted position by manually operating the head lifting mechanism 26 via the recording operation mechanism 28. Thus, the reliability of the recording operation is ensured.

As shown in FIG. 10, after the recording operation mechanism 28 moves the head operation member 70 by the transmission control member 68, the recording operation mechanism 28 is actuated by the urging force of the tension coil spring 69.
Transmission control member 68 is moved in the arrow b ₁ direction, the rotation operation lever 67 is returned to the initial position.

[0090] Further, the optical disk device 1, by which power is supplied to the coil 130 of the plunger 104 of the lock mechanism 29, the metal piece 131 attraction is weakened by the magnet 129 is moved in the arrow b ₂ direction. Locking mechanism 29, by a metal strip 131 is moved in the arrow b ₂ direction, the switching member 103 is rotated in the arrow c ₁ direction, the locked state of the head operating member 70 is released.

[0091] Then, the optical disk drive 1, the head lifting mechanism 26 with the be moved in the arrow b ₁ direction by the urging force of the tension coil spring 71 head operating member 70 is operated to move the magnetic head 36 is light The magnetic disk 6 is returned to the retracted position separated from the recording area.
That is, the optical disc device 1 is configured such that the power is supplied to the plunger 104 of the lock mechanism 29, thereby
The state shown in FIG. 7 is shifted to the state shown in FIG.

As described above, the optical disc device 1
Since the recording operation mechanism 28 for manually operating the head lifting mechanism 26 is provided, it is not necessary to secure a space for installing driving means such as a motor for driving the head lifting mechanism 26 and a control circuit in the apparatus. It is possible to reduce the overall thickness and to reduce the manufacturing cost.

Further, according to the optical disk device 1,
At the time of recording information, the magnetic head 36 is moved down with respect to the magneto-optical disk 6 by manual operation via the recording operation mechanism 28, so that recording can be performed more quickly than when a driving means such as a motor is used. The operation can be started.

The optical disc apparatus 1 is capable of performing a recording operation when an initial state in which the disc cartridges 3 and 4 are not mounted in the cartridge mounting section and when a pit disc cartridge 4 which is not recordable is mounted in the cartridge mounting section. Since the transmission control member 68 of the mechanism 28 is disabled by the lock mechanism 29, malfunction of the head lifting mechanism 26 can be reliably prevented.

In the optical disk device 1, when recording information on the magneto-optical disk 6, after the magnetic head 36 is lowered to the recording position, the lock mechanism 29 is moved to the head by the recording operation mechanism 28. Since the operation of the elevating mechanism 26 is disabled, the magnetic head 36 is reliably prevented from being erroneously moved to the retracted position during the recording operation, and the reliability of the recording operation is ensured.
