Abstract

PURPOSE:To make a magneto-optical disk drive device thin by a structure wherein the height position of a cartridge inside the device is fixed and a spindle motor is moved up and down. CONSTITUTION:When a cartridge 102 is inserted into a magneto-optical disk drive device, a shutter 104 is slid to the transverse direction and the shutter 104 is opened. When the cartridge 102 reaches a prescribed position, its fitting to a loading slider 106 is released and the slider 106 is slid. At this time, a spindle motor 101 is attached to a motor base 108. In addition, the motor 101 is raised according to the movement of the slider 106 and a disk 112 is chucked. When the cartridge 102 is to be ejected, the slider 106 is slid and the motor 101 is lowered. Then, the lock of a shutter opening and shutting pin 103 is released, and the cartridge 102 is discharged by the springy force of a coil spring 114.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading mechanism between a disk and a spindle motor of a magneto-optical disk drive device.

[0002]

2. Description of the Related Art In recent years, computer external recording devices based on a magneto-optical recording system have begun to be put into practical use. This device heats the recording medium to near the Curie temperature by spot-irradiating a laser beam from the optical head onto the surface of the recording medium,
Data is recorded by controlling the direction of the magnetic field generated by the magnetic head. Conventionally, it has been developed as a device separate from the computer main body, but it can be considered to be installed in a laptop or notebook computer in the future. At present, the floppy disk drive device has a height of 1 inch or less, and the height is an important problem in the magneto-optical disk drive device. However, when the cartridge is loaded in the device as in the current case, The large dead space makes it difficult to reduce the device thickness.

[0003]

Therefore, the present invention is intended to solve such a problem, and an object of the present invention is to provide a thin optical device which can be mounted on a laptop type or notebook type personal computer. It is to provide a magnetic recording / reproducing apparatus (a 3.5-inch disk drive with a height of 1 inch or less).

[0004]

A magneto-optical disk drive device according to the present invention comprises: (1) In the magneto-optical disk drive device, a spindle motor used for rotating the disk is movable in a rotation axis direction with respect to the disk. When the cartridge accommodating the disc is inserted into the magneto-optical disc drive device, the spindle motor is raised to the disc chucking surface for chucking, and the cartridge is taken out from the magneto-optical disc drive device, It is characterized in that the spindle motor is lowered to a position where interference with the cartridge can be avoided and the cartridge is removed.

(2) In the magneto-optical disk drive device, a spring force is used to move the spindle motor in the rotation axis direction.

(3) In the magneto-optical disk drive device, when a cartridge accommodating a disk is inserted into the magneto-optical disk drive device, the positioning pin used for positioning the cartridge in the magneto-optical disk drive device is After the cartridge is inserted, the spindle motor moves up to the disk chucking surface, with a structure integral with a spindle motor used for rotating the disk, and the spindle motor is movable in the rotation axis direction with respect to the disk. At the same time as chucking, the cartridge is positioned by the positioning pin.

【Example】

(Embodiment 1) FIG. 8 shows a conventional cartridge loading type magneto-optical disk drive device. In this case, the spindle motor 301 is fixed to the magneto-optical disk drive device, and after the cartridge 302 is inserted to a predetermined position, the chucking surface of the disk 303 housed in the cartridge 302 is changed to the chucking surface of the spindle motor 301. It descends to a position that matches the king plane. For this reason, the volume required for the vertical movement of the cartridge 302 becomes a dead space, which has been a serious problem in reducing the thickness of the magneto-optical disk drive device.

Next, FIG. 1 shows a front view of a magneto-optical disk drive device according to an embodiment of the present invention. In this example,
The maximum outer shape is 146.0 mm in length, 101.6 mm in width, and 25.4 mm (1 inch) in height. In addition,
3 (a) and 3 (b) and FIGS. 3 (a) and 3 (b) are side views of the spindle motor in the raised position and the lowered position, respectively.
The perspective view of the structure of the spindle motor and the motor base is shown in FIG.

When the cartridge 102 is inserted into the magneto-optical disk drive device, the shutter opening / closing pin 103 provided in the magneto-optical disk drive device engages with the shutter 104 of the cartridge 102, and the cartridge 1
Shutter opening / closing pin 10 as 02 is further inserted
Since 3 slides along the guide groove, the shutter 10
4 slides in the lateral direction to open the shutter 104.
When the cartridge 102 reaches a predetermined position, the locking pin 105 is pushed by the entire end surface of the cartridge 102 so that the engagement with the loading slider 106 is released, and the loading slider 106 slides due to the repulsive force of the coil spring 107. At this time, the spindle motor 101 is attached to the motor base 108,
Is engaged with the cam groove 110 of the loading slider 106 by the slide pins 109 on both sides. Further, since the motor base 108 engages with the guide bar 111 and the spindle motor 101 can move in the rotation axis direction, the spindle motor 101 rises according to the movement of the loading slider 106 to chuck the disk 112. .. At the same time, the shutter opening / closing pin 103 is locked by the loading slider 106.

When ejecting the cartridge 102, the eject button 113 is pressed to slide the loading slider 106, and the spindle motor 101 is first lowered. Next, the shutter opening / closing pin 103 is unlocked, and the shutter opening / closing pin 103 is released.
The cartridge 102 is ejected by the spring force of the coil spring 114 connected to the cartridge 102, the loading slider 106 is locked by the locking pin 105, and the ejecting operation of the cartridge 102 is completed. Therefore, the volume required for the vertical movement of the spindle motor 101 becomes a dead space, which is significantly reduced as compared with the case where the cartridge 102 is vertically moved.

(Embodiment 2) FIG. 5 is a front view of a magneto-optical disk drive apparatus according to an embodiment of the present invention.
6 (a) and 6 (b) are side views showing the states before and after the positioning of the cartridge 202, and FIG. 7 is a perspective view showing the configuration of the spindle motor and the motor base. In this example, the basic configuration and basic operation are equivalent to those shown in the first embodiment. Positioning pins 215 for positioning the cartridge 202 are installed on the motor base 208.
Spindle motor 2 when cartridge 202 is inserted
01 moves up and chucks the disk 212, and at the same time, the positioning pin 215 positions the cartridge 202. Further, when the cartridge 202 is ejected, the spindle motor 201 descends, and at the same time, the positioning of the cartridge 202 is released.

[0012]

As described above, according to the present invention, the height position of the cartridge in the magneto-optical disk drive device is fixed and the spindle motor is moved up and down to improve the space efficiency. By performing the positioning of the cartridge integrally with the vertical movement of the spindle motor, a compact magneto-optical disk drive device of 3.5 inch disk type and 1 inch height can be realized.
