Table 8-20. Page Code 80h Test Description

DESCRIPTION
The same tests as described in Table 8-19. The
self test is also SCSI Routine 01h.
Data is written into the data buffer and passed
from the data buffer to the MTU. The MTU
returns the data to the formatter through both the
analog and digital check circuitry. No tape motion
is required.
Data is written into the data buffer and passed
from the data buffer through the formatter. No
tape motion is required.
Tape is positioned at Load Point and 4 tones are
written. They are each 4 meters in length and
written with the order of Erase Tone, IBG Tone,
Tape Mark (TM) Tone, and Density ID (DID)
Tone.
Tape is positioned at Load Point and 4 meters of
Erase Tone, IBG Tone, TM Tone and DID Tone
are written. The tones are read back in reverse
direction and a rewind is performed.
Tape is positioned at Load Point and 4 tones of 4
meters each is written. The tones are; Erase Tone,
IBG Tone, TM Tone and DID Tone. The tape is
then rewound. At Load Point, another 4 tones are
written (same as above), but this time instead of
just rewinding, the tones are read in the reverse
direction.
An 'all zeroes' data pattern is replicated in the
data buffer and blocks are written to tape until
Logical EOM is detected. The first block written
is 255 bytes in length. Each succeeding block
length is incremented by one. All data is read in
both the forward and reverse directions.
Tests the drive logic, photo sensors, loader mech-
anism, and the tachometer pulse generation.
Tests the ACL/FACL loader mechanism and
photo sensors.
