Patent ID: 8526136

Claim:
A computer system comprising: a non-transitory computer-readable medium; and a processor in operable communication with the non-transitory computer-readable medium, the processor being adapted to: select a first data group in an access sequence of a plurality of data groups stored on a tape medium based on which data group in the plurality of data groups has a beginning closest to a current position of the tape medium; select a second data group in the access sequence based on which remaining data group in the plurality of data groups has a beginning closest to an end of the first data group in the access sequence; modify the access sequence to generate a modified access sequence based on which position of the last data group in the access sequence corresponds to a shortest total seek time; repeat the modifying of the access sequence until the modified access sequence is the same as the previous modified access sequence; and calculating a plurality of total seek times for the access sequence based on a time required to move between the plurality of data groups.
