ABSTRACT:
A speed sensing roller is mounted in position on a digital tape cassette apparatus for frictional contact with a length of magnetic tape within a cassette housing through that one of the apertures in the cassette housing which is located closest to one of the cassette hubs operating as the takeup hub during tape travel in a forward direction. Utilizing a tape speed signal generated by a speed sensor driven by the speed sensing roller, a closed-loop servomechanism controls a pair of motors coupled directly to the respective cassette hubs to afford constant tape speed. The servomechanism is associated with a tape tension control circuit which causes controlled energization of a supply side one of the hub motors during tape travel in either direction in order to maintain proper tape tension. Various other circuit means are provided for optimum tape transportation in the digital tape cassette apparatus.
