ABSTRACT:
A speed control signal for a record segment is generated from starting speed and starting time information signals, an ending speed information signal, and a signal indicative of the duration of the segment. Provision is made for "pre-roll" (stopping the tape ahead of the exact cue point). Duration can be entered directly or computed from start and end times. The speed control signal is applied to a capstan servo, while a cue logic servo controls a reel servo.
