ABSTRACT:
In a tape drive during a transition to a stand-by mode, a tape is wound under control of a processor (e.g., CPU) until duration of a time interval between moments when rotational positions of the reels change decreases to a pre-determined threshold. Thereafter, in the stand-by mode, the processor switches control over the tape drive to a low-power logic circuit (e.g., PLC) and enters a power-save mode.
