<p>PURPOSE:To surely perform erasing, reproducing, etc. with easy operations by detecting the recording start position mark given to a tape and controlling the tape recorder. CONSTITUTION:The recording command from an operation part 3 causes a control part 2 to electrically give a recording start mark to the endless tape of an endless tape recorder 1. Next, when recording is accomplished and is finished, the recorder 1 erases the unnecessary records having been recorded from the recording end point up to the recording start point until it detects the recording start mark through the control part 2. At the same time, the control part 2 lets the recorder 1 stop according to the recording mark detection of the recorder 1. On the other hand, when a reproduction command is applied from the operation part 3 to the control part 2, the recorder 1 does not stop until it detects the recording start mark even if the reproduction end instruction is given. Thereby, the recording, erasing and reproducing are accomplished surely with the simple operations.</p> |
