A tape drive assembly ( 20 ) for the transmission of data relative to a magnetic storage tape ( 278 ) includes a tape head ( 260 ), a cartridge receiver ( 268 ) and a controller ( 44 ). The cartridge receiver ( 268 ) selectively receives a cartridge ( 54 ) having a lapping tape ( 478 ) that laps the tape head ( 260 ). The controller ( 44 ) dynamically adjusts one of (i) a tension of the lapping tape ( 478 ) relative to the tape head ( 260 ), (ii) an oscillation frequency of the tape head ( 260 ) relative to the lapping tape ( 478 ), and (iii) a lateral velocity of the lapping tape ( 478 ) relative to the tape head ( 260 ). The controller ( 44 ) can use an algorithm to adjust these conditions. The algorithm can be based on the pliability of the lapping tape ( 478 ), a curvature of the tape head ( 260 ) and/or the grit of the lapping tape ( 478 ). In addition, or in the alternative, the algorithm can be based on at least one of an output of the tape head ( 260 ), a resolution of a signal from the tape head ( 260 ), an error rate in reading of data by the tape head ( 260 ) from the storage tape ( 278 ), an error rate in writing of data by the tape head ( 260 ) to the storage tape ( 278 ), and a signal-to-noise ratio from the tape head ( 260 ).
