Claim Text:
1. A method for operating a tape drive, comprising: identifying, by one or more computer processors, a first extent to which a magnetic tape has been used; identifying, by one or more computer processors, one or more modules of a tape head for which a tape head wrap angle should be modified; responsive to determining, by one or more computer processors, that the first extent to which the magnetic tape has been used is less than a first specified threshold, moving one or more tape supports of the tape drive to a first configuration to increase contact pressure between one or more modules of the tape head and the magnetic tape and burnish at least a portion of the magnetic tape; subsequent to the moving one or more tape supports of the tape drive to the first configuration, identifying, by one or more computer processors, a second extent to which the magnetic tape has been used, wherein the second extent represents a greater amount of usage of the magnetic tape than the first extent; and responsive to determining, by one or more computer processors, that the second extent to which the magnetic tape has been used exceeds a second specified threshold, moving one or more tape supports of the first tape drive to a second configuration to decrease contact pressure between one or more modules of the tape head and the magnetic tape.
