Claims

[Scope of utility model registration request]

(1) A control mechanism that separately controls recording mode, playback mode, and high-speed rewind mode, and a control mechanism for controlling the magnetic tape.
j. a detection opening trace installed between the green lights and detecting the recording signal and a distinguishable start end identification signal recording section; The magnetic recording/writing device switches to the playback mode after operation, and the magnetic cape is transferred only in one direction. A magnetic dip re-coupling device having a mechanism,
Connect the playback signal of the magnetic chip playback device to the magnetic recording and playback device. 1. At the time of dubbing, the non-recording playback device controls this 0th control mechanism. Set the record mode to 7 and put the magnetic f6 tape! The starting end identification number KJi is recorded for a predetermined period of time at intervals of 6.1,
5. The magnetic tape reproducing device finishes recording the identification signal when the magnetic recording and reproducing device is set to the recording-1 need. A magnetic taper singing "i" recording and reproducing device, characterized in that it is configured to start reproducing from point L.

(2) The magnetic tape recording and reproducing apparatus according to claim (1), wherein the start end identification signal recording section is a non-signal recording band of a predetermined section.

(3) The magnetic tape recording and reproducing apparatus according to claim (1), wherein the start end identification signal recording section records a frequency signal outside the audio frequency band.
