WITE32 Release Notes Version 3.20

In the WITE32 version 3.20, four following items are displayed on the drop-down list in the Disk Chuck Type

dialog box:

• Unknown disk chuck

• Fixed clamping

• Vacuum clamping

• Air clamping

You must select the disk chuck, which is installed on your spinstand before you will start the machine.

Note:

Only the chuck with the fixed clamping was supported in the WITE32 version 3.11.

3.4 PRML Chip Adapter Software

New architecture of the PRML channel software is introduced in the WITE32 version 3.20. According to the

new architecture the PRML software consists from three parts:

• Driver for a PRML chip

• Driver for the Guzik chip adapter board, developed for the chip

• Universal Chip Adapter user interface.

The customers can develop their own PRML chip drivers using the Driver Development Kit (DDK) provided by

Guzik Technical Enterprises. The DDK includes all necessary tools, software libraries and documentation for

developers. The drivers for Guzik chip adapter boards are included in WITE32 installation.

Please contact Guzik Technical Enterprises sales department for the documentation on DDK.

Three of the latest PRML drivers for the RC6600, and 88C7500P channels on Chip Adapter 2000, and the

88C7500M channel on Chip Adapter 4000 are developed using the new DDK.

Please request the chip drivers for these channels from Guzik customer support. Do not install beta versions of

the chip drivers (see section 1.1 for addition information about updated PRML chip drivers).

This does not affect the driver for the 88C7500M channel on Chip Adapter Interface 2000, since this driver is not

based on the DDK.

3.5 Chip Adapter User Interface

The Chip Config dialog (see Figure 8) is the universal user interface to control PRML channels, which are

designed using the DDK technology.

To open the Chip Config dialog box select the Tests | PRML Chip Config | PRML Chip Config menu item from

the WITE32 Engineering Dashboard main menu. The PRML Chip Opt item is assigned to the last WITE32

Dashboard soft button. Click on the S button to the left of the last soft button to invoke the Chip Config dialog

box.
