ABSTRACT:
A digital video tape drive and a method of controlling frequency drift in the tape drive. The tape drive includes a helical scan recorder in which the recording drum motor and the capstan motor arc synchronized to the frequency of a long-term reference clock derived from a reference signal (e.g. an MPEG program clock reference (PCR) signal or system clock reference (SCR) signal) embedded in digital video data to be recorded by the tape drive. The drum motor is also phase locked to the long-term reference clock signal. In addition, the drum motor is synchronized to a reference clock derived from the reference signal during playback of the digital video data.
