Hga Cassette Parameter Configuration - Agilent Technologies E5035A Operation Manual

HGA Cassette Parameter Configuration

After initializing the system, the cassette parameter setup menu will pop up, this will
require you to specify the size of the cassette's HGA and cassette part number. This setup
menu is necessary to activate the VEE measurement program and remind the user that such
parameter setup is required. If the user decides to change the cassette parameter setup
during operation, click on [Cassette Parameter] from the Spinstand Menu and reset the
parameters.
Basically there are two purpose for setting the cassette parameters. First is to know the
reference point. The write offset and read offset's reference point must be specified. This
becomes the track's center point. The second purpose is to let the system know the HGA
and cassette size so as to prevent the head from bumping into the shroud. Size of cassettes
varies with each Agilent part number.
NOTE If the Agilent part number is not registered on the system's software an error
"hpe5022_ERROR_NSUP_HGA_ CASSETTE" will appear on the display. The software
does not support the cassette. In such case, the system's software must be upgraded.
1. After initialization, the 'Cassette Parameter Setup' menu will pop up as shown below.
This allows the user to set the cassette parameters.
