Abstract

A tape recording system for connection to a controller of a floppy disk data recording system for recording data in a stream on a recording tape in the same format that data is recorded on a disk by the disk data recording system. A control processor responds to sensing a beginning-of-stream indicator on the tape (a) by causing an initial gap to be erased in the tape stream adjacent the beginning-of-stream indicator and (b) by next providing an initial beginning-of-segment index pulse to the controller. The control processor responds to the combination of (a) a gate signal from the controller provided simultaneously with a formatting signal and (b) the sensing that the length of tape transported past the transducer head following provision of a beginning-of-segment index pulse corresponds to the length of a concentric track on a disk (a) by providing an end-of-segment index pulse to the controller, (b) by next causing an inter-segment gap to be erased in the tape stream and (c) by finally providing another beginning-of-segment index pulse to the controller. The controller responds to the beginning-of-segment index pulse from the control processor by providing to the transducer head…
