Abstract

The magnetic tape cassette of the present invention has the opening portion into which the head drum having the rotary head is inserted. The pair of tape guide members which guide the tape-like record medium so that the record medium is helically wrapped around the head drum are provided in the inside of the opening portion so as to be able to swing independently. Thus, when the head drum is inserted into the opening portion, the two tape guide members are brought in circumferential contact with the peripheral surface of the head drum accurately. Therefore, the recording and/or reproduction can be reliably carried out, which can increase reliability of the magnetic tape cassette.
