A magnetic tape recording and/or reproducing apparatus which comprises a tape cassette mounting portion and a rotary head portion which are relatively movable toward to and separating from each other, the rotary head portion being provided with a recording/reproducing head which is adapted to project in the radial direction due to the centrifugal force of the rotation of the head, and the rotary head portion can approach relatively toward the tape cassette mounting portion on which the tape cassette is mounted, and the recording/reproducing head being projected by the centrifugal force contacts with the magnetic tape running within the tape cassette.
A tape cassette is also provided which comprises a front wall having a circular arcuate recess as viewed in the plan view, with the inner surface of a portion of the front wall defining the arcuate recess being formed as an arcuate drum surface along which the tape contacts and slides during the running condition, the portion of the front wall forming the drum surface is formed to have a head inserting slot, and the head inserting slot is adapted to receive the recording/reproducing head therethrough for contacting with the tape.
