Claims

[Claims for Utility Model Registration] (1) Means for generating an end detection signal when detecting the end of a set tape, and means for driving the tape in response to the end detection signal during recording mode to detection means for detecting a boundary between a leader tape section and a magnetic tape section and generating a boundary detection signal; and a detection means for detecting a boundary between a leader tape section and a magnetic tape section and generating a boundary detection signal; a transporting means for transporting the tape at a constant speed; and after the tape is transported by the transporting means, an erasing head acts on the tape while transporting the tape in the same direction as the tape running direction during the recording mode. and fade-out control means for gradually increasing the alternating current erasing current flowing through the erasing head. (2) The detection means operates a playback head on the tape while transporting the tape in the reverse direction at a constant speed in response to the end detection signal, and compares the output signal level from the playback head with a predetermined level. The tape recorder according to claim 1, characterized in that: (3) The detection means operates a playback head on the tape while transporting the tape in the reverse direction at high speed in response to the end detection signal, and compares an output signal level from the playback head with a predetermined level. The tape recorder according to claim 1, characterized in that: (4) The detecting means drives the tape in the reverse direction for a predetermined period of time in response to the end detection signal, and then drives the tape in the tape running direction in the recording mode while moving the playback head to the tape. 2. The tape recorder according to claim 1, wherein the level of the output signal from the playback head is compared with a predetermined level.
