A magneto-optical storage card is produced using magneto- optical recording medium. The magneto-optical card consists of a substrate and a multilayer film structure. The card substrate has the groove geometry pattern comprising the track pitch, the groove width, and the groove depth. As the magneto- optical recording medium, the RE-TM magneto-optical recording material is used. The card substrate is made of glass, on which the preformatted pattern is formed by a photolithography technology, the preformatted pattern is used for servo tracking and for pre-recording information for optical data storage. The prototype drive system for the magneto-optical card is capable of driving, writing/reading and erasing the MO card. The card has high reliability for information storage.
