録再生装置。[Claims for Utility Model Registration] Detecting means for detecting the end of a first recorded portion recorded on a magnetic tape; and detecting means for detecting the end of a first recorded portion recorded on a magnetic tape; a magnetic tape drive means that drives in the recording direction, stops in response to a second drive signal applied when stopping, and drives in the rewind direction in response to a third drive signal applied during rewind playback; recording means including a recording head for making a desired recording on the magnetic tape; erasing means including an erasing head for erasing the recorded portion recorded on the magnetic tape; and a control means for controlling the operations of the tape drive means and the erasing means, and the control means, when receiving a follow-up superimposition recording mode signal, supplies a first drive signal to the magnetic tape drive means to erase the magnetic tape. The first one that drives the tape to run.
In the running drive state, when the detecting means provides a detection signal indicating the end of the first recording portion, the magnetic tape driving means is configured to cause the second magnetic tape driving means to
a second means for applying a drive signal; and a third means for applying a third drive signal to the magnetic tape drive means for a predetermined time after the second means stops running the magnetic tape; When a start signal is given, the erasing head is inactive and the recording head is active for the predetermined period of time, and after the predetermined period of time, both heads are activated and the magnetic tape drive means is activated. 1 drive signal, and a second recorded portion recorded on the magnetic tape after the recording start signal is applied is a leading portion of the first recorded portion for the predetermined time. A magnetic recording and reproducing device characterized in that recording is superimposed on the ending portion.
