Data smoother for a streaming cartridge tape drive.

摘要

A data smoother for a streaming cartridge tape drive includes a circuit for generating a clock signal and a circuit for comparing the phase of the clock signal with the phase of the data signal input to the data smoother. The frequency of the clock signal is increased when the data signal leads the clock signal by an amount which is directly proportional to the phase difference between the clock signal and the data signal, and the frequency of the clock signal is decreased when the data signal lags the clock signal by an amount which is directly proportional to the phase difference between the clock signal and the data signal.
