摘要：
On a pit information surface (22d) of a read-only optical disk (22), a protective layer (22f) against a flying or sliding magnetic head (3) for a magnetic field modulation opto-magnetic disk is formed. Reproduction of the optical disk (22) is performed by sliding the magnetic head (3) on the protective layer (22f). Without need to keep the magnetic head away from the disk surface during reproduction, the cost and size of the optical disk device is reduced and fast seek is realized. The magnetic field modulation opto-magnetic disk and its cartridge (32) are standardized. A user-friendly optical disk system is provided.
摘要（中）：
在只读光盘（22）的凹坑信息表面（22d）上，形成了用于磁场调制光磁盘的防飞溅或滑动磁头（3）的保护层（22f）。 通过在保护层（22f）上滑动磁头（3）来执行光盘（22）的再生。 在再现期间，不需要将磁头保持在远离磁盘表面的状态，所以光盘装置的成本和尺寸减小，实现了快速寻找。 磁场调制光磁盘及其盒（32）被标准化。 提供了一种用户友好的光盘系统。
