Title: Tape handlers

Filed: 1975-07-30
Abstract: 1522626 Digital magnetic tape handlers, SPERRY RAND CORPORATION 30 July 1975 31913/75 Heading G4C A digital magnetic tape handler comprises a tachometer 15, Fig. 1, responsive to the speed of the tape 10a, an oscillator circuit, Fig. 2, controlled in response to an output signal from the tachometer 15 for clocking the transfer of data from or to a read/write head 20, and a threshold circuit 37 controlling the oscillator circuit to render it operative when tape speed reaches, from rest, a predetermined fraction (e.g. 50%) of its full speed. In this way data may be written on to or read from the tape while the tape is accelerating and decelerating, thus reducing the magnitude of the acceleration and deceleration required on either side of a given inter-record gap. Writing and reading on to and from the tape are controlled by respective phase-locked oscillators 28, 27 of the oscillator circuit, the oscillator 28 being locked to the tachometer output signal whereas the oscillator 27 is locked to the frequency of the data signals read from the tape. The synchronizing input of oscillator 27 is coupled to the error signal output line of oscillator 28, in order that oscillator 27 may be readily locked to the data signal frequency. The threshold circuit 37 receives, via a line 24, digital input signals from the tachometer 15 which are fed in parallel to one-shots (47, 48), Fig. 3 (not shown) which control respective flip-flops (53, 54), the outputs 45, 46 of the respective flip-flops (53, 54) providing enabling signals to the respective phase-locked oscillators 27, 28. One-shot (48). is adjusted so that its "active" time is equal to the duration between adjacent timing pulses from tachometer 15 at the predetermined fraction of full speed, whereas the active time of one-shot (47) is slightly less than this. In operation of the tape handler from rest, after each pulse sent from tachometer 15, one-shot (48) will reset before the next pulse arrives, causing flip-flop (54) to remain reset. When the predetermined fraction of full speed is reached, one-shot (48) will not have time to so reset and flip-flop (54) will be set, enabling phase-locked oscillator 28 via output 46. As tape speed further increases, flip-flop (53) becomes set and enables phase-locked oscillator 27 via output 45. The relative magnitudes of the active times of one-shots (47, 48) ensure that the error signal output from oscillator 28 is available at the synchronizing input of oscillator 27 when the latter is enabled at the start of a reading operation.
