Abstract

PURPOSE:To record and reproduce information while a tape is contained hermetically in a tape housing by forming an arc-shaped recessed part at some part of the front wall of a cassette tape housing and by running and tape in slide contact with the inside projected surface of the recessed part. CONSTITUTION:Respective layers of a tape 18 are laminated at the part of a recessed part 11g in the order of a base 18a, a recording layer 18b, and a reflective layer 18c from the housing front wall 11c side of the recessed part 11g, and when the tape 18 runs sliding in contact with the inside projected surface of the recessed part 11g, the housing front wall 11c and the base 18a of the tape are brought into contact with each other to protect the recording layer 18b of the tape. Since the reflective layer 18c is provided as the innermost layer, a fine hole as information recorded in the record ing layer 18b is reflected to the reflecting layer 18c to achieve reproduction.
