Aufzeichnungs-/Wiedergabesystem für eine magneto-optische Platte

摘要

A magneto-optical disc (D) having an opticalmagnetic recording layer (2) formed on the surface of a transparent base plate (1) opposite to its beam incident surface (1b). A layer (5; 25) excellent in lubriciousness is formed in superimposition on the opticalmagnetic recording layer (2) to enable the magnetic head to be in direct sliding contact with the disc surface to provide for stable recording and improved recording performance as well as to reduce adverse effects caused by deposition of foreign matter such as dust and dirt.
