Description

Disc cartridge

The present invention relates to a cartridge, and more particularly to a disk cartridge capable of selectively receiving a disk of diameter 120mm, 80mm or less.

In recent years, as the disks have become high density and high density, the influence of dust, fingerprints or scratches on the disks has increased. That is, the size of the light spot irradiated for recording or reproducing information is reduced while the information is densely and highly integrated on an existing disk of the same size, and even if a small substance is present on the disc, the information by the light spot is lost. It acts as an obstacle to recording or playback.

Therefore, in order to protect a data area in which information can be recorded or reproduced from dust, fingerprints, or scratches, a disc cartridge is provided that is capable of recording and reproducing information by an optical pickup device in the disc drive so as to be rotatably received. Is widely used as a recording medium for multimedia such as video and sound.

Referring to FIG. 1, a disc cartridge 10 accommodating a disc D divided into a clamping area D1 in which no information is recorded and a data area D2 in which information can be recorded and reproduced is combined and received. The disk (D) is inserted into an inner space formed by combining the upper and lower cases 11 and 12 and the upper and lower cases 11 and 12 to form an inner space in which (D) can be rotated. ) And a turntable and a clamper (not shown) installed in the disk drive to clamp the clamping region D1 of the disk D in the vertical direction. An optical pickup device (not shown) is formed to be connected to the accommodation holes 11a and 12a formed in the lower cases 11 and 12 and the accommodation holes 11a and 12a, so that an optical pickup device (not shown) is provided in the radial direction of the disk D. It includes a shutter 14 for opening and closing the opening holes (11b) (12b) for exposing the disk (D) so as to linearly move in and out by the shutter opening and closing means (not shown).

The holder 13 is provided with a locking protrusion 13a and a pressing member 13b formed integrally connected to both sides facing each other. The locking protrusion 13a is elastic to the locking grooves 11c and 12c formed in the upper and lower cases 11 and 12, respectively, when the holder 13 is coupled to the upper and lower cases 11 and 12. When the holder 13 is detached from the upper and lower cases 11 and 12, the locking projection 13a is locked by pressing the pressing member 13b in a direction opposite to each other. 12c).

When the conventional disc cartridge 10 configured as described above is loaded into the disc drive device, the shutter 14 is coupled to one end of the shutter opening and closing means installed in the disc drive device to support the force of the disc cartridge 10 being loaded. It is opened while being moved in one direction. Next, the turntable and the clamper are coupled to each other in the accommodation holes 11a and 12a of the disk D with the clamping area D1 of the disk interposed therebetween to clamp the disk D.

Then, the optical pickup device linearly reciprocates and transfers light to the data area D2 in the radial direction of the disk D rotated by a rotating means such as a motor, that is, along the opening holes 11b and 12b. Investigate and record or reproduce the information.

However, such a conventional disc cartridge is generally manufactured to accommodate a disc having a diameter of 120 mm. Therefore, in order to use a disk having a diameter of 80 mm or less, it is troublesome to use a separate disk cartridge.

As an example of a method for solving the above problems, the contents disclosed in Korean Laid-Open Publication No. 1999-0060059 are shown in FIG. 2. Referring to FIG. 2, two first and second support levers 30 and 40 are installed to selectively use different types of discs having diameters of 120 mm and 80 mm. Support is solved the above problems. However, the support levers 30 and 40 are operated separately to support the disc.
