8200 Format

If the tape is written in 8200 format, the tape drive can perform forward file-search operations at 10 times the nominal tape speed and backward file-search operations at 7.5 times the nominal tape speed.

Rewind Tape Speed

Table 6-4lists maximum rewind times for the tape drives for four sizes of EXATAPE 8mm data cartridges. Rewind time starts when the initiator issues a REWIND (01h) command and ends when the tape drive returns a Command Complete message (for a non-immediate rewind). All times listed in the table assume the following:

The tape is positioned at LEOT when you issue a REWIND command.

The drum has not stopped rotating.

Tape tension has not been released.

Reposition Time

Reposition time starts when the initiator issues a command that stops the tape drive’s motion control system and ends when the tape is repositioned, at nominal speed, so that the next byte of data can be transferred. Reposition time is independent of any interface delays.

Reposition time for the tape drive ranges from 1.2 sec to 1.5 sec.
