摘要： 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.

摘要： A dielectric part 4 comprising a nitride layer 7 and an oxide layer 8, laid one upon the other, is formed on a data-recording layer 3. A light-transmitting layer 5 is boned with adhesive to the dielectric part 4. Since the dielectric part 4 is interposed between the data-recording layer 3 and the light-transmitting layer 5, the organic material of the data-recording layer 3 does not diffuse into the adhesive that bonds the light-emitting layer to the dielectric layer 4. Additionally, the data-recording layer 3 is not deteriorated due to the oxygen plasma generated during the process of forming the oxide layer 8, because the oxide layer 8 is provided on the nitride layer. Since the nitride layer 7 has a thickness of 10 nm or less, it does not influence optical enhancement effect.
摘要翻译：在数据记录层3上形成包括氮化物层7和氧化物层8的电介质部分4.透光层5用粘合剂粘合到电介质部分4上。由于电介质部分4插入在数据记录层3和透光层5之间，数据记录层3的有机材料不会扩散到将发光层粘合到电介质层4的粘合剂中。另外，由于在氮化物层上设置有氧化物层8，所以在形成氧化物层8的过程中由于氧等离子体而导致数据记录层3不劣化。由于氮化物层7的厚度为10nm以下，因此不影响光学增强效果。

摘要： The present invention relates to a cartridge and a method that can sweep away dust or the like from a recordation medium housed in the cartridge in a simple way without adversely influencing recording and replaying of the recordation medium. The cartridge includes a shutter opposed to a surface of the recordation medium, a cleaner member, a support for supporting the cleaner member, and a sweeping mechanism actuated upon opening and closing movements of the shutter. The support pivots in a plane substantially in parallel to the surface of the recordation medium when the sweeping mechanism is actuated. When the sweeping mechanism moves forwards, the cleaner member moves without contacting the recordation medium surface. When the sweeping mechanism moves backwards, the cleaner member moves in contact with the recordation medium surface to clean the recordation medium surface.
