ABSTRACT:
A signal generator for producing signals indicative of the speed of tape driven reel to reel in a tape cassette transport in lieu of timing signals recorded directly on the tape is used to control the reel motors that drive the cassette. The tape-engaging drive wheel is designed to minimize slippage between the moving tape and the drive wheel so that the generator output accurately reflects tape speed.
