Title: Tape timing apparatus
IPC: G11B27/32
Filed: 1977-03-18
Abstract: 1532124 Tape position indicator AMPEX CORP 18 March 1977 [19 March 1976] 11675/77 Heading G5R Tape position indicating apparatus has a tape drive tachometer 11, Fig. 2, which produces first electrical pulses corresponding to tape movement, the first pulses being passed to a timing pulse generator 15, Fig. 3, having a counter 71 acting as a divider for the first pulses with one output of the counter giving timing pulses which are processed in a circuit 17 to drive a tape position (timer) display in response thereto, and control track pulses read off the tape are received in the circuit 15 wherein a phase difference between the control track pulses and the tacho pulses results in reset of the counter 71 and thus adjustment of the phase of the timing pulses sent by generator 15 to circuit 17 and the tape position display. The tape position may be indicated as a video frame count and/or as a time in seconds; in the first case (as illustrated) the 150 Hz tacho pulses are divided by five by counter 71 so that generator 15 gives a U.S. standard 30 Hz frame rate output to circuit 17; in the second case (not shown) counter 71 divides by 150 to give a 1/sec output. As shown, the binary 2 output of divide-by-five counter 71 passes via inverter 93 to form the input to circuit 17 and the same signal forms a control track gate pulse line B, Fig. 4 (not shown), which extends over the 4, 0 and 1 count state intervals of counter 71 and which gate pulse is applied to input 107 of a D-type flipflop 109 having an input 111 receiving the control track pulses. Occurrence of a control track pulse during the zero state interval of counter 71 has no effect on the phase of the timing pulses sent from generator 15 to circuit 17, whereas a control track pulse occurring during the 4 or 1 state of counter 71 causes reset thereof (via output 113 of flipflop 109 and OR gate 81) thereby adjusting the phase of the timing pulses; a control track pulse occuring outside the control track gate pulse interval, i.e. during the 2 or 3 state of the counter, has no effect on the timing pulse phase since flipflop 109 is then disabled. The apparatus operates for either direction of tape travel the tachosensor 11, Fig. 2, having a first photoelement 21 yielding the pulses counted by counter 71 and a second photoelement 23 giving pulses 90 degrees out of phase with those from element 21. A direction sensor 19 responds to both elements 21, 23 and gives a high output to circuit 15 and a low output to circuit 17 for forward tape drive and vice versa for reverse tape drive.
