ABSTRACT:
A tape recorder has an operating mode in which a magnetic tape is run at a speed higher than an ordinary reproducing speed, a magnetic head is in sliding contact with the magnetic tape, and a desired tape position is searched. In this operating mode, the magnetic tape is run initially at a first speed higher than the ordinary reproducing speed, for example triple that speed, for a predetermined period of time after an operating switch that sets the operating mode is turned on. Then, if the operating switch remains continuously turned on after the elapse of this predetermined period of time, the magnetic tape is run at a second speed which is higher than the first speed, for example 16 times the ordinary reproducing speed. In this manner, the tape speed is automatically switched from a high-speed and therefore efficient search mode in which a selected section of the tape is searched to a still higher speed in which the tape is rapidly advanced to a different section of the tape.
