ABSTRACT:
The moving data storage media mode/direction change optimization apparatus makes use of information received concerning the mode and direction of the next operation to be performed by the data storage system to efficiently reposition the media in a single repositioning operation. In the case where the data storage media is a magnetic tape, the tape control unit receives information concerning the mode and direction of the next operation to be performed prior to the completion of the tape transport automatic repositioning cycle. The tape control unit signals the tape transport to abort the standard repositioning operation and instead to initiate a new repositioning operation which repositions the magnetic tape based on the mode and direction of both the presently executing operation and the next operation. This use of a single repositioning operation, taking into account the mode and direction of the timewise subsequent operation, significantly reduces the amount of time required to reposition the magnetic tape to a point appropriate for the next operation.
