  • Page 14 2.3.2.1 Dialog Box Layout and Tab Pages The parameters in the Product Parameters dialog box are grouped into three tab pages: • The Disk tab page. This page contains controls and parameters related to disk geometry such as disk type, minimum radius, maximum radius, direction of rotation and speed (RPM), device options, disk working area, skew angle parameters, start and stop options.
  • Page 15 2.3.2.2 Changes of the Disk Type Control The following two changes are introduced in the Disk Type control starting from WITE32 version 3.11: • The Disk type 2.756 Inch (70 mm) is now supported. This disk type is added to the Product Parameters dialog box.
  • Page 16 Cartridge Angle Parameter is Added to the V2002 Product Parameters Dialog Box In previous versions of WITE32, you had to combine the cartridge angle with the head loader angle and store the resulting value in the spinstand EEPROM. The cartridge angle (0 or –10 degrees) was added to the head loader angle in respect to the XY stage of the spinstand (the V2002 head loader has a 45 degree angle) and specified in the Tooling Angle text box on the Tooling Parameters tab of the Spinstand Parameters dialog box of WDCP2002.
  • Page 17 2.3.2.4 Micro Actuator Parameters In order to start working with Micro Actuator it has to be enabled and configured. The new controls are added to the Product Parameters dialog box.

  • Page 18: Xy Alignment Test

    All Head Parameters controls are made read-only, since they are shown on the XY Alignment configuration form for the reference purpose only. Starting from WITE32 version 3.11 you must use the Product Parameters dialog box of the WDCP2002 program to change these values.

  • Page 19: The Write With Retries Operation

    The Write With Retries Operation A new type of operation is implemented in WITE32 revision 3.11: the Write With Retries operation. This is a special case of the write operation when the RWA shuts down the write gate in the sectors, in which the spinstand detects that the Position Error Signal (PES) exceeds the specified tolerance.

    Miscellaneous 1. The maximum number of result records in the WITE32 result processor is doubled so that more test results (up to 200,000) can be accommodated at run-time. 2. The new signal WOPEN (Write Operation Enable) is added to the list of available sources for RWA output scope points.
  • Page 23 WITE32 version 3.10 and earlier, generic internal names are used in the dialog box. For example, “WrtFlux” is used for the flux reversal value in the WriteFlux operation test of WITE32 version 3.10, which is renamed to “Mflux/s” in WITE32 version 3.11: Figure 19 Parameter Caption In WITE32 version 3.10...

    7. After performing the Y-limit Adjustment there is no software validation of Y-stage positioning and the Y-limit screw can be hit. In the new version of WITE32, the software always checks if the destination position is reachable before the Y-stage starts moving such that the Y-stage does not hit the screw and the warning message is shown when the specified destination position is out of range.
