2.2 New Adjacent Track Interference Module (WATI)
The new Adjacent Track Interference module (WATI module) is added to WITE32 package. This module contains
one test – the Adjacent Track Interference test. Please refer to the WATI Module Users Guide (P/N 02-107268-02)
for the description of the WATI module and the test. The WATI module requires a license and possible hardware
upgrade; please contact sales@guzik.com and provide them your RWA and Spinstand EEPROM Dump information
to determine whether your test system requires an upgrade, and to request a quote for the license.
2.3 Spinstands and Servo

2.3.1 New Servo Control Dialog Box

The new Servo Control dialog box is added in WITE32 rev 3.11. It can be opened by selecting the Control | Servo…
menu item in the WITE32 Engineering Mode Dashboard.
Figure 9 New Servo Control Dialog Box
This dialog box has two check box controls:
1. Disable Servo Control if Loop is Unstable. If this check box is enabled, WITE32 turns off the servo control
in case the signal from the head becomes unstable. The warning message “Servo control is turned off. Check
that the signal from the head is stable” is displayed once, and the servo control is turned off. If this check
box is disabled, WITE32 will keep the servo control enabled regardless of the quality of the signal from the
head. This may result in the recurring error messages during head positioning, however, the system will try
to control the head position using servo whenever it is possible. It is recommended to enable this option in
the production environment, such that testing the heads producing poor signal can be finished in non-servo
mode. This control is available only for Guzik V2002 spinstands. For all other spinstands this check box is
disabled.
2. MA Enable – This control is reserved for future use with Micro Actuator.

2.3.2 V2002 Product Parameters Dialog Box Modifications

The Product Parameters dialog box contains the parameters o f the Head and the Media under test. For V2002
spinstand, you can open the Product Parameters dialog box by selecting the Configure | Device… menu item in the
WITE32 Engineering Mode Dashboard, pressing the Run Alignment Program button in the Device Configure dialog
box, and pressing the Edit Product Parameters… button on the Equipment tab of the WDCP2002 program.
The layout of the Product Parameters dialog box for V2002 spinstand is changed and new parameters are added in
WITE32 version 3.11.
