Abstract
A tape cassette includes an MIC (Memory-In-Cassette) installed inside the center section of the label surface, and a case capable of housing the magnetic tape. A switch circuit board is installed in the front part of the chassis parallel to the inner side of the front panel, and a communications antenna is mounted on this switch circuit board. When the cassette is loaded in the chassis from the cassette insertion slot, the MIC is in proximity to the front of the communications antenna and wireless communications between the antenna and MIC are carried out with high accuracy. By efficiently installing an MIC in a tape cassette having little excess space such as DAT (digital audio tape recorder) cassettes, an increase in the number of parts and the number of assembly processes can be avoided and highly accurate reading and writing of control information on the MIC in the cassette can be performed.
