Claims

[Scope of utility model registration request]

In a playback device that plays back a magnetic tape on which PCM audio signals for a plurality of songs and a cue control signal and song number data are recorded at the beginning of each song,
at least a constant speed high-speed travel control means, a medium-speed travel control means, a low-speed travel control means, a means for specifying a cueing position, and a cueing position specified by the means based on the cueing control signal. means for detecting, means for causing the high-speed running control means to run the magnetic tape until the specified cue position is detected by the means, and braking control of the magnetic tape when the specified cue position is detected. and after the magnetic tape is stopped by the means, the medium-speed running control means and the low-speed running control means reciprocate the magnetic tape, and the low-speed running control means detects the specified cueing position again, and the magnetic tape is stopped. 1. A music selection control device comprising: means for controlling braking of a tape.
