Note 1. Tape is threaded immediately after the cassette tape is inserted into the VIR when the semi transparent tape is not detected.
2. When the leader or trailer tape is detected during the threading, the VIR will go into the short-FF or short-rewind mode and
the mechanical brake shoe is applied for braking.
3. A mechanical brake system works when the VTR is in the threading, unthreading, standby, tape protection operation
or power-off conditions. Mechanical brake system is not used during the normal operation.
