Claims

[Scope of utility model registration request]

Used in a magnetic recording/reproducing device in which an auxiliary member made of high magnetic permeability material and shaped like an arc along the tape attached to the drum is movably provided between a standby position and an operating position along the tape. A tape cassette, wherein a recess with openings on the bottom and front sides is provided between a supply reel and a take-up reel wound with a magnetic tape having a magnetic film that can be perpendicularly magnetized on a base material, the recess A tape cassette having a shape that allows the auxiliary member to be relatively fitted into the recess when the tape cassette is mounted at a predetermined mounting position, and to allow the auxiliary member to come out of the recess during tape loading.
