WITE32 Release Notes Version 3.20
3.3.2 Revision 2 of V2002 Spinstand Head Alignment
The new revision of the Head Alignment test for the V2002 spinstand is implemented in the WITE32
version 3.20. The Head Alignment Revision 2 calculates the coordinates of the disk center more accurately. The
new test finds the track, written by a reference head, with the accuracy improved from 100 µm to 10µm.
The Head Alignment Revision 2 can be used with Servo Revision 3 RWA only. If you have an RWA equipped with
Servo Revision 2, WITE32 will use the first revision of the Head Alignment test.
Note:
If you use an RWA equipped with Servo 3 and your production sequence includes the Head Alignment test, you
do not need to modify the production sequence. You still need to open the Head Alignment Rev.2 dialog box,
however, (see Figure 5) to specify the parameters of the head alignment.
Figure 5: Head Alignment Rev.2 Dialog Box
The following controls are located in the Head Alignment Rev.2 dialog box:
• The Service Track Parameters frame allows you to specify the track profile range and the step being used to
measure the head parameters (such as Track Width and WR Offset).
The From text box Specifies the starting offset of the track profile. The absolute value
cannot exceed the maximum offset.
The To text box Specifies the final offset of the track profile. The absolute value
cannot exceed the maximum offset.
The Step text box Specifies the step by which the head is moved between offsets to
build a track profile. This value cannot be smaller than the device
step.
