Abstract

Linear tape has a tape directory information regarding written data on the tape medium in order to provide a fast access to desired target data on the tape. The directory information is mostly available, but once it is corrupted somehow, it usually takes a lot of time to recover the information, because all written data must be read. This method provides a fast recovery method of tape directory on linea tape medium by selecting the fastest way from among three different recovery ways.
