Chapter 7. 3590 High Performance Cartridge Tape and Extended High Performance Cartridge Tape
The 3590 tape drive has a bidirectional read/write head with a recording format of 256 tracks for Exx models and 128 tracks for Bxx models. Both series of models concurrently processes 16 tracks per group. The bidirectional head writes 16 tracks from the load point to the physical end of tape. It then writes 16 tracks from the physical end of tape back to the load point. To eliminate the rewind operation, fully written tapes are always positioned at the load point.
Attention: Do not degauss a cartridge tape. Degaussing the tape will erase the servo tracks and make the cartridge unusable. Run a Data Security Erase if the data on the tape needs to be physically erased. This physically overwrites the data on the tape without damaging the servo tracks.
