Notes
|
* The actions of the tape drive can be divided into four distinct phases:
Phase 1: Load time — the amount of time required to insert a cartridge in the drive, load the tape and prepare to read, write or search.
Phase 2: Average file access time — the amount of time required to search from the beginning of the tape to the midpoint; does not include load time.
Phase 3: Maximum rewind time — the amount of time required to rewind the tape from the end to the beginning of the tape. The average rewind time is the time to rewind a tape from the midpoint to the beginning, i.e. one-half of the maximum rewind time.
Phase 4: Unload time — the amount of time required to eject the cartridge from the drive.
