Writing dummy indices on a tape medium partition

摘要

A request for writing a first index information to a first partition of a serial storage medium of a serial system is received. The serial storage medium includes a first partition for writing the first index information including a first index position, a second partition for storing a data set, the data set including a second index information including a second index position, a memory for determining the second index position, and a module for writing the first index position. A beginning position of the first index is written on the first partition. A determination is made whether the beginning of the first index position is proximate to the second index position. In response to the beginning of the first index position being proximate to the second index position, an interrupted index position is registered. A dummy index is written to the first partition at the interrupted index position.

主权项

1. A method for storing data on a storage medium, the method comprising:
receiving a request for writing a first index information to a first partition of a tape medium of a tape drive, the tape medium including:
the first partition for writing the first index information starting at a first index position,a second partition for storing a data set, the data set including a second index information starting at a second index position,a non-volatile memory for storing the second index position, anda module for writing the first index position; writing a beginning portion of the first index information on the first partition at the first index position; determining whether the beginning portion of the first index information is proximate to the second index position; registering, in response to the determining that the beginning portion of the first index information is proximate to the second index position, an interrupted index position; and writing a dummy index to the first partition starting at the interrupted index position to create a physical misalignment between the first index information on the first index partition and the second index information on the second partition.
