APPARATUS AND METHOD FOR CONTROLLING TRANSPORTATION OF TAPE MEDIUM

摘要

An apparatus, computer readable medium device, and method for controlling transportation of a tape medium. A determination is made whether to execute a backhitch operation in response to writing a data set to tape from the buffer. If not, a determination is made whether a transaction size at which data is transferred from the buffer to the tape is less than a buffer size. If so, then a determination is made of a a new speed and whether a current speed is different from the determined new speed. If so, then a backhitch is initiated.

1. An apparatus of controlling transportation of a tape medium during data writing to the tape medium, comprising:
a buffer; a controller that performs operations, the operations comprising:
determining whether to execute a backhitch operation in response to writing a data set to tape from the buffer;determining whether a transaction size at which data is transferred from the buffer to the tape is less than a buffer size in response to determining not to execute the backhitch;determining a new speed of the tape in response to determining that the transaction size is less than a buffer size;determining whether a current speed is different from the determined new speed; andinitiating a backhitch in response to determining that the current tape speed is different from the determined new speed.
