Abstract

PURPOSE:To obtain an optical cassette tape, by enclosing a slender tape on which the nonreversible recording is optically carried out into an housing together with a pair of reels and providing the tape with an optical head to irradiate the laser beam. CONSTITUTION:A tape 15 has a linear travelling part between guides 14a and 14b, and an optical head 20 is provided on a front wall 10c to record and reproduce an information on the tape. A flange 22 has an airtight bearing structure, and a modified Newell system or a reel drive system is applied to secure the contactless travelling of the tape. The tape 15 is obtained by applying a metallic film of Te-As- Se on a plastic base in a thickness of about 100Angstrom or applying a mixture of carbon and nitrocellulose. Preferably, a gas absorbent is put previously into the housing.
