Filed: 1972-06-16
Abstract: 1381780 Measuring iriterblock gap INTERNATIONAL BUSINESS MACHINES CORP 16 June 1972 [24 June 1971] 28191/72 Heading G4H The interblock gap (IBG) on a data carrying tape is determined by detecting the beginning (21) and end (22) of the gap using a tape head, generating marking points in the gap by an optical encoder mounted on the drive capstan, calculating times between the various markings and using these and a computer to calculate the IBG. The times are derived from clock pulses having a much higher repetition rate than the output of the encoder at normal tape running speed. The time To between the start of the gap (21) and the first encoder pulse 36A is measured and then the time T between each successive encoder pulse, these being summed as The time T K+1  between the last encoder pulse and the end 22 of the gap is also measured. Knowing the distance dK on the tape corresponding to one encoder pulse, the IBG=(D) can then be calculated from The tape may run steadily at normal speed or may be braked to a halt and immediately accelerated again during the measurement, discrepancies in the calculated values for the IBG indicating tape slip. The programmes and computer layout necessary for the calculations are described.
