METHOD FOR OPTIMIZED TAPE TENSION ADJUSTMENT FOR A TAPE DRIVE

摘要

PD91-0070 A method for selecting an optimal operating tension of a motor driven tape in a tape drive is disclosed. The tape is loaded into the tape drive. A test signal is applied to record test information onto the tape while the tape tension is varied concurrently in a prescribed manner for testing. The recorded test information is read immediately to provide a test readback signal. The test readback signal is processed to determine a functional relationship between the test readback signal and the varying tape tension. An operating tape tension value is selected based upon the functional relationship. The selected operating tape tension is implemented on the tape drive in the form of a command signal to a motor means of the tape drive. Figure 1.
