Reducing time to reposition tape to write index

Abstract:

Aspects of the present disclosure relate to a method for reducing repositioning time within tape systems. A request to reposition to a target file within a tape medium can be received. A determination can be made that a previous command issued to the tape system was a write and that an index corresponding to the write has not been written. In response to determining that the previous command was the write and that the index corresponding to the write has not been written, a first file mark, the index after the first file mark, and a second file mark after the index can be written.
