摘要

A tape cassette system for any tape-shaped recording medium such as film, recording strips. Magnetic tape etc. consists essentially of a tape cassette with a housing (44), the external dimensions of which are adapted to a known cassette system, and a protective / holding sleeve (43) for the recording medium (18) wound at least into a roll of tape. Housing and cover are separated or separable and are put together. The housing and case are provided with devices for correctly inserting the case into the housing and for inserting the tape into the device. The housing is designed with a vertical joint connection (47, 48) for opening / closing. The sleeve can be designed to be separable from the tape roll or rolls. In addition, the housing can be provided with a flap-like opening (50) for removing the protective / holding sleeve (43) without the tape rolls. The housing (44) is preferably manufactured as a precision part and the casing as a cheap part. Individual features concern the complete tape cassette, the cover and the housing. The system can be used as a replacement for any known cassette system in the entertainment or professional sector of signal recording and reproduction.
