Auto Alignment
Overview
Auto alignment is used to determine the center position of the spindle. Once the auto
alignment is completed, the alignment data will be saved in the non volatile memory of the
spinstand. This data contains each individual data of the up face and down face HGAs. See
"Auto Alignment" on page 317 for basic concept of the auto alignment.
NOTE
When you perform the auto alignment using the VEE measurement program (Test
Environment) or auto alignment functions of the "hpe5022_32.dll," the spinstand must
have the initial alignment data in the non-volatile memory because the spinstand cannot
perform the erase and write operation in the auto alignment process without the alignment
data. If the alignment data is lost by some trouble, you must first restore the data using the
recovery disk (shipped with the spinstand) and then overwrite it by the auto alignment.
Procedure
1. To open the Auto Alignment menu, click [Auto Alignment] button.
