  • Abstract
    Magnetic tape velocity variations are determined with a read while write head by measuring the frequency difference between the write current signal and the playback signal from the read gap. This frequency difference may correspond to either tape acceleration or velocity, depending on the period at which the tape velocity is varying, and it can be measured by observing beat frequencies on a storage oscilloscope.
