H-4.3.4.5 M5:LOCAT: Tape locating time measurement
Measure the time required for tape locating from the wrap-1 BOT position to the wrap-1 PEOT
position. (Unit: 1/10 sec)
The measured data is stored in either of two areas for normal and E cartridges.
After rewinding the tape to the wrap-1 BOT, servo MPU measures the Locating execution time
from wrap-1 BOT to sector 95.
H-4.3.4.6 M6:REWND: Tape rewinding time measurement
Measure the time required for tape rewinding from the wrap-1PEOT position to the wrap-1
BOT position. (Unit: 1/10 sec)
The measured data is stored in either of two areas for normal and E cartridges.
After locating sector 95, servo MPU measures the Rewinding execution time from sector 95 to
wrap-1 BOT.
H-4.3.4.7 M7:D.S.E: DSE time measurement
Measure the time required for DSE from the wrap-1 BOT position to the wrap-2 PEOT position.
(Unit: 1/10 sec)
After rewinding the tape to the wrap-1 BOT, measure the DSE command execution time neces-
sary to reach the wrap-2 PEOT position.
H-4.3.4.8 M8:UNLD: Cartridge unloading time measurement
If the tape is not at the wrap-1 BOT position, rewind the tape.
Unload the cartridge and measure the following operation times during unloading. Both normal
and E-cartridge are able to be measured.
Tape winding time (from wrap-1 BOT to immediately before unthreading)
Measure the time from when the start of rewinding from the wrap-1 BOT position begins
until immediately before unthreading. (Unit: 1/10 sec)
Unthreading time
Measure the time from the start of unthreading until the end of threading. (Unit: 1/10 sec)
Loader operation time
Measure the time from when the loader starts rising until it ejects the cartridge (by the ejec-
tion arm). (Unit: 1/10 sec)
H-4.3.4.9 M9:CLEAN: Cleaning time measurement
Load a cleaning cartridge and measure the time from when loader starts loading the cartridge
until its ejects the cartridge after cleaning. (Unit: 1/10 sec)
The tests can be set using the following parameters:
DIAG parameter 1: For “M2:TPPFM”, “M3:AC/PS” and “M4:MODCH”, specify a location sector from 1
to 75.
The minimum value is 5.
The maximum value for a normal length cartridge is 60.
The maximum value for an external length cartridge is 75.
