Magnetic tape cassette

摘要

A magnetic tape cassette intended for applications such as digital recording where extremely tight tolerances are imposed on the amount of widthwise deviation of the tape. A partition member, dividing the cassette into a recording and reproducing region and a tape winding core accommodating region, is molded separately from the two halves of the shell of the cassette. The partition member has a partition wall having guide walls protruding forwardly therefrom symmetrically with respect to the center line of the cassette. The pair of guide walls closest to the center line have front portions of reduced height so that the upper and lower portions thereof do not contact the cassette halves.
