Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording and / or reproducing apparatus having an information recording medium loading mechanism.

[0002]

2. Description of the Related Art Conventionally, in optical disk devices and magneto-optical disk devices, the pitch width formed on an optical disk is 0.5 μm and the numerical aperture NA of the objective lens is 0.45.
And the wavelength of the laser light to be irradiated is 780 nm. Such a conventional optical disk device, etc.
When recording or reproducing an information signal, the working distance when focusing between the optical disc and the movable part of the actuator that holds the objective lens should be larger than the error that occurs when the optical disc or the objective lens is driven. Was possible. Therefore, the optical disk device, etc.
Even when the optical disc is inserted into the main body of the device during operation and non-operation, the optical disc mounted and the movable part of the actuator on which the objective lens is mounted do not collide. It was possible.

[0003]

In recent years, the pitch of optical discs has been narrowed in order to increase the density, so that the numerical aperture NA is large and the wavelength of the laser light emitted is also short. . Therefore, the optical disk device, etc.
The working distance between the optical disk and the movable portion of the actuator that holds the objective lens becomes shorter, and the optical disk and the objective lens may collide with each other. Also,
As the optical disc becomes narrower in pitch, the spot diameter on the optical disc becomes smaller.Therefore, the damage on the optical disc caused by the contact between the optical disc and the objective lens does not affect the recording or reproduction of the information signal. It is larger than before.

Here, when the optical disc is inserted in the main body of the optical disc device or the like, and the optical disc is in a standby state where information signals are not recorded or reproduced or when the main body of the device is turned off. If is held close to the objective lens, the optical disc may come into contact with the objective lens due to a disturbance such as an impact on the apparatus body. Further, even in the standby state, it is not preferable to continuously apply the servo signal to the optical pickup so that the optical disc and the objective lens maintain a constant distance from the viewpoint of suppressing the power consumption of the entire apparatus.

Therefore, according to the present invention, by providing a loading position different from the loading position of the optical disc when recording or reproducing the optical disc and when ejecting the optical disc, the collision between the optical disc and the objective lens provided in the actuator is prevented. It is an object of the present invention to provide a recording and / or reproducing apparatus that can prevent the recording and / or reproducing apparatus.

[0006]

In order to solve the above-mentioned problems, a recording and / or reproducing apparatus according to the present invention comprises a loading mechanism for conveying an information recording medium inserted in the apparatus body, and the above-mentioned information recording. A rotation driving mechanism for rotating the medium; and an optical pickup for recording or reproducing an information signal on or from the information recording medium, wherein the loading mechanism has an unloading position for inserting or removing the information recording medium, The information recording medium is conveyed between a loading position for recording or reproducing an information signal on the information recording medium and an intermediate position for holding the information recording medium in the main body of the apparatus while separating the information recording medium from the optical pickup. .

While the optical pickup device 7 is moved in the radial direction of the optical disc 3 by a drive mechanism whose details are omitted, the optical pickup device 7 reproduces an information signal for the optical disc 3.

In the recording / reproducing apparatus 1 as described above, the slide cam 20 of the loading mechanism 5 is moved to the front surface 2a side of the apparatus body 2 by the feeding mechanism when the optical disk 3 is not inserted into the apparatus body 2. Has been done. Therefore, the disc holding portion 10 includes the horizontal guide portion 2 in which the guide pin 17 is formed in the guide groove 21 of the slide cam 20.
It is guided by the inclined guide portion 2 and the inclined guide portion 23, moves upward from the chassis 9, and is positioned at the unloading position on the front surface 2a side of the apparatus main body 2.

Next, as shown in FIG. 5, the recording / reproducing apparatus 1 detects the insertion of the optical disc 3 into the apparatus main body 2 by the cartridge detection switch, and then the CPU
In response to this control signal, the slide cam 20 of the loading mechanism 5 is moved to the rear surface 2c side of the apparatus main body 2 by the loading motor of the feeding mechanism. As a result, the disc holding portion 10 holding the optical disc 3 moves to the guide pin 17
From the horizontal guide portion 22 of the guide groove 21 to the inclined guide portion 2
Guided to 3. As a result, the disc holding unit 10
The guide pin 17 is the inclined guide portion 23 of the guide groove 21.
And slides down to the chassis 9 side, as shown in FIG. Therefore, the optical disc 3 held by the disc holding portion 10 is held at the loading position close to the objective lens of the optical pickup device 7 arranged in the chassis 9. After that, the optical disc 3 has the clamping plate attached to the drive shaft of the spindle motor 30 of the disc rotation drive mechanism 6 and the disc holding portion 1.
It enters through the central opening of 0 and is rotatably held. Then, in this state, the operation section 13 of the apparatus main body 2 is operated to record or reproduce the information signal.

Then, when recording or reproduction on the optical disc 3 is stopped or ended and an instruction to eject the optical disc 3 is issued by the operation unit 13, the recording / reproducing apparatus 1 causes the clamping plate of the disc rotation drive mechanism 6 to operate. The loading mechanism 5 is retracted from the disc holding unit 10 and then loaded.
The slide cam 20 is moved to the front surface 2a side of the apparatus main body 2 by the feeding mechanism. As a result, the disc holding unit 10
The guide pin 17 is the guide groove 21 of the slide cam 20.
Slides from the inclined guide portion 23 to the horizontal guide portion 22 and rises above the chassis 9, and the front surface 2a of the apparatus main body 2
