<p>This invention is directed to a tape cassette (1) in which a tape body is wound across a pair of tape reels (5, 6) rotatably supported by the cassette body (4). At the cassette body (4), there are provided a first write protect mechanism (31, 32) provided in correspondence with the position where there is provided a write protect mechanism provided at another tape cassette loaded with compatibility with respect to a recording/reproducing apparatus into which a tape cassette is loaded, and a second write protect mechanism (33) provided at the position which is not in correspondence with the position where write protect mechanism provided at the other tape cassette is provided, wherein the first write protect mechanism (31, 32) is in write protect state at all times. Thus, when there is loaded a tape cassette where recording of information signals is carried out by another recording format into recording/reproducing apparatus corresponding to only a tape cassette of a specific recording format of tape cassettes different in the recording format, recording of information signals with respect to this tape cassette is inhibited to realize protection of already recorded data. <IMAGE></p> |
