Problems solved by technology

[0004] When various disc drives are used in corresponding various disc cartridges, storage space can be a problem and it is even more inconvenient to have to determine which disc drive corresponds to a given disc cartridge
This identification is especially difficult when the cartridges are of similar size

Embodiment Construction

[0030] Next, a solution of the disk drive device of the present invention will be described with reference to FIGS. 1-14. Figures 1-14 show examples of disk drives capable of driving a DVR cartridge 1 for recording and / or reproduction, a DVD-RAM cartridge 2, and a bare DVD or a DVD-ROM not placed in a cartridge. Other discs 3.

[0031] The DVR disc box 1 that utilizes blue laser to carry out high-density recording on the optical disc for so-called DVR is shown in Figures 5 and 6; Figure 5A is a perspective view seen from the front of DVR disc box 1, and Figure 5B is viewed from the back 6A is a plan view of the back, and FIG. 6B is a cross-sectional view taken along line A-A of FIG. 6A.

[0032] DVR disc case 1 comprises: the optical disc 10 of outer diameter 12cm, thickness 1.2mm installed in the case 1a;

[0033] As shown in Figures 6A and 5B, a pair of positioning holes 1c and 1d including a circular hole and an oval hole are formed on the back of the case 1a, the pair of...

Abstract

An object is to drive a plurality of types of disc cartridges, in different formats but with similar external dimensions. A disc drive apparatus is configured to use a single spindle motor (32) to drive a first disc cartridge (1), having a first cartridge (1a) housing a first disc (10) and a first pair of positioning holes (1c, 1d) in the first cartridge (1a), as well as a second disc cartridge (2) having a second cartridge (2a) housing a second disc (13) with the same outer diameter as the first disc (10) and a second pair of positioning holes (2c, 2d) in the second cartridge (2a); positioning shaft location means (40, 41) are provided; when the first disc cartridge (1) is driven, these positioning shaft location means (40, 41) position the positioning shafts (40a, 41a) in positions corresponding to the first pair of holes (1c, 1d), and when the second disc cartridge (2) is driven, the positioning shaft means (40, 41) position the positioning shafts (40b, 41b) in positions corresponding to the second pair of holes (2c, 2d).

Description

technical field [0001] The present invention relates to a disk drive apparatus for recording and / or reproduction using a disk cartridge in which an optical disk, magneto-optical disk, magnetic disk or other disk is placed, and more particularly to a disk drive apparatus capable of driving a variety of disk cartridges. Background technique [0002] In the prior art, drives for recording and / or reproducing on media types of the same format but different sizes, such as Betacam and DV cassettes, are made to accommodate Cassettes and magazines of various sizes, whereby the cassettes and magazines are driven by the same drive means by means of a mechanism for positioning the horizontal movement of the shaft or other means. [0003] However, in disc cases having different formats, although for example the outer diameter of the discs placed in the case is the same 12 cm, there is a slight difference in planar dimensions, height dimensions, and similarity of the positioning hole port...
