US07178156B2 Disk cartridge having identification element and disk drive apparatus which recognizes the identification element 有权
具有识别元件的磁盘盒和识别识别元件的盘驱动装置

Disk cartridge having identification element and disk drive apparatus which recognizes the identification element
Abstract:
A disk cartridge has a reflection portion to identify a kind of a disk in the disk cartridge. A disk drive apparatus has an optical detector to identify the kind of the disk by irradiating a beam to the reflection portion and detecting the reflected beam. The disk cartridge and the disk drive apparatus provide identification marks for identifying the kind of the disk by varying the angle and amount of a beam reflected from the reflection portions on the disk cartridge. Therefore, the kind of a disk and the type of a disk format are identified as well as the storage capacity of the disk.
Abstract(Chinese):

盘盒具有用于识别盘盒中盘的种类的反射部分。 磁盘驱动装置具有光学检测器，用于通过将光束照射到反射部分并检测反射光束来识别光盘的种类。 盘盒和盘驱动装置通过改变从盘盒上的反射部分反射的光束的角度和量来提供用于识别盘的种类的识别标记。 因此，识别磁盘的种类和磁盘格式的类型以及磁盘的存储容量。
