Abstract

A tape cartridge ( 54 ) for use in a tape drive ( 46 ) having a tape head ( 260 ) includes a cartridge housing ( 272 ), a cartridge reel ( 274 ) and a tape ( 278 ). The cartridge reel ( 274 ) is rotatably secured to the cartridge housing ( 272 ). The tape ( 278 ) is secured to the cartridge reel ( 274 ). The tape ( 278 ) can include a storage tape ( 278 D) that stores data and a lapping tape ( 278 L) that laps the tape head ( 260 ). In one embodiment, the storage tape ( 278 D) and the lapping tape ( 278 L) are spliced together. The ratio of storage tape ( 278 D) to lapping tape ( 278 L) can be at least approximately 0.01:1. The lapping tape ( 278 L) can include a diamond material having a grit of between approximately 0.1 micron and 1.0 micron. In one embodiment, the tape ( 578 ) can include a first lapping tape ( 578 L 1 ) and a second lapping tape ( 578 L 2 ) that has a different grit than the first lapping tape ( 578 L 1 ). In another embodiment, the tape ( 678 ) also includes a cleaning tape ( 678 CL) that cleans the tape head ( 260 ).
