4 Requirements for Use
Refer to
Load Time
The time required to load the data cartridge and position the tape to LBOT after the data cartridge is inserted is approximately 60 seconds. When loading a tape, the tape drive spaces forward from PBOT and determines the following:
The tape format. The format will be either 8200, 8200c, 8500, 8500c, or unknown.
The adaptive servo parameters. This process enables the tape drive to read tapes produced by different manufacturers, tapes that are aged and worn, and tapes written by other 8mm tape drives.
The length of the tape in use. The tape drive autosizes the data cartridge to determine the tape length. For more information about autosizing, refer to the
Unloading Data Cartridges
You can unload a data cartridge by either pressing the unload button or by issuing an UNLOAD (1Bh) command. This section describes what happens when the unload button is pressed. For information about using the LOAD/UNLOAD (1Bh) command, see the
If a data cartridge is loaded and the tape drive is error free, the tape drive performs the following actions when you press the unload button:
Completes any command that is currently in progress
Writes any buffered information to tape
Writes EOD (except in 8200 format)
Rewinds the tape to physical beginning of tape (PBOT)
Unloads the tape from the tape path and ejects the tape
In addition, the tape drive has several unload button options for “normal,” “fast,” and “super fast” unload operations.
