Title: Tape cartridge
IPC: G11B23/28
Filed: 1988-04-13
Abstract: PURPOSE:To certainly prevent wrong erasure of recorded information by providing a locking piece which can be operated for displacement from the outside to a switching piece for opening and closing a detect hole and causing a restrictive wall on a main body side to receive the locking piece displaced after the switching piece is moved to a write inhibit position. CONSTITUTION:A locking piece 27 which can be operated for displacement is provided to a switching piece 11 for opening and closing a detect hole 10 and a restrictive wall 30 is provided on a main body case 1 side in corresponding to the locking piece 27. When the locking piece 27 is displaced to the inside of the case by pushing the piece 27 with a rod-like body S from the outside of the case after the switching piece 11 is moved to a write inhibit position, the piece 27 is received and supported by the restrictive wall 30. Since the switching piece 11 does not move to a write enable state even if returning force is applied to the piece 11 in such state because of the locking piece 27 acting as a prop resisting the returning force of the switching piece 11, the movement of the switching piece 11 to the write enable state is certainly prevented. Thus wrong erasure can be prevented certainly.

Abstract: PURPOSE:To correctly distinct the correctable and not correctable error at write-in, by the error judgement of Delay of Start (DOS) signal through double check. CONSTITUTION:The capstan 8 is turned via the drive circuit 3 according to the write-in instruction from the write-in control circuit 2. Further, when the magnetic tape 8 is a given running speed, the DOS signal is produced from the DOS detection circuit 6. On the other hand, the judgement circuit 5 sets the specified timer time to the time-counting circuit 9 according to the write-in command of the circuit 2. Further, when the DOS signal from the circuit 6 reaches within the timer time, it is judged as normal state and write-in processing is instructed to the circuit 2. At the judgement of unusual state, the circuit 5 further sets the timer time to the circuit. When DOS signal reaches within this time, the circuit 5 sets the correctable error and when timer-over is detected, noncorrectable error is reported to the upper rank unit 1. The double check of the DOS signal can correctly distinct the correctable and noncorrectable errors, noncorrectable state is not taken place frequently, allowing the write-in with high reliability.
