In this paper an attempt is made to develop an efficient tape transport mechanism required for high-speed data transfer. The mechanism is controlled by a microcomputer, which is a party in the data transfer operation. A commercially available transport system has been adopted for this purpose, with simple modification. During data search operation the tape speed is faster than the speed in normal Read/Write operation. At the same time, the Read/Write head position is adjusted in accordance with the tape speed. The system includes facilities for detecting the beginning and the end of the tape, and switching off the amplifier for read and write operation. Taking into account the delay for signal transfer and the time for motor torque, a tape motion velocity profile has been generated. This is used to obtain start, stop and interblock gap length.
