Agilent Cassette Part Number
The Agilent E5022/E5023 contains the information of the dimension of the Agilent
cassette, this is to prevent the head and the cassette from bumping into the spindle. Enter
the down head's Agilent part number of the HGA cassette to be used. If an upper face of
the head is to be used then enter its corresponding Agilent part number.
Agilent part number is labeled on the HGA cassette. An example would be
"E5010-61121". Parameters can be set by the "hpe5022_hgaCassette" function. If a new
cassette is to be used, whose information is not in the system an error
"hpe5022_ERROR_NSUP_HGA_CASSETTE" will occur. In this case the DLL (Dynamic
Link Library) for the cassette must be installed.
Inhibit Area Margin
An inhibit area or marginal distance has to be specified to keep the head and cassette from
bumping into the spindle. Parameters are set by the "hpe5022_inhibitMargin" function.
This value is set at 1mm in the VEE Demo program.

Data Area
The number of tracks and track area of a media can be specified by the data area. This can
be done by setting the radius of the innermost track, track interval and the maximum track
number. The outermost track number is set to zero. To compute for the number of tracks
add 1 to the maximum track number. This also defines the center position for each track.
Parameters are set by the "hpe5022_dataArea" function.
