摘要 |
A disk cartridge and a disk drive apparatus. The disk cartridge has a reflector to identify the type of disk, and the disk drive apparatus has an optical emitter/detector to irradiate light on the reflector and detect light reflected from the reflector to identify the type of disk. A large number of identification marks can be provided by changing the angle of reflection and the amount of light reflected from the reflector. Accordingly, disks of various capacities, products and formats can be individually identified. |
