WITE32™
Version 2.33
9/1/99
Introduction
The 2.33 release
introduces new features, and fixes
bugs found, in the WITE32 2.32 release. (This document
uses the WITE32 2.32 release notes as a base line for comparison.)
New Features
- PRML chip adapter software now supports M16+ B PRML chip.
- Popcorn Test can now run in hard sector mode.
- WITE32 now supports all the SP (Side Position) Interfaces.
Fixed Bugs
The following bugs have been fixed:
- For a computer without Visual Basic 6.0 installed, pressing the setup button for the Spectrum Analyzer test triggers the following error message (found in ver. 2.32),
WPROF: Error: Class not registered.
You need the following file to be installed on your machine. MSSTDFMT.DLL. Abort/Retry/Ignore
NOW: This file has been included in the installation and this error does not occur.
- Clicking the From, To, and Step data fields alternately in the Write-Read Offset Test configuration dialogue box causes the values to change due to a rounding error.
NOW: The rounding error in the Write-Read Offset Test is fixed.
- There is an error in reporting modulation when a test is run through the Spectrum Analyzer (reported = 25% vs. actual = 1%).
NOW: The reported modulation is the same as the actual measured modulation.
Modifications
- During startup of WITE32, there were too many "Power On/Power Off" events on the Head Amplifier that may damage/kill ESD sensitive heads.
NOW: The number of "Power On/Power Off" events on the Head Amplifier is reduced to 4 to 6 per startup.
- The Offtrack Performance Test is modified in the following ways:
- Three new parameters are measured, reported to the database,
and reported on the graph window. These parameters are
On track Error Rate, Error Rate @ +X%, and Error
Rate @-X%.
On track Error Rate Minimum measured Error Rate
value
Error Rate @ +X% Error Rate values measured at the
distance X% of the track pitch from the center of the track,
which is equal to 0 or WROffset value, depending on the Center
at read Offset position checkbox value
Error Rate @-X% Error Rate values measured at the
distance -X% of the track pitch from the center of the track,
which is equal to 0 or WROffset value, depending on the Center
at read Offset position checkbox value
 - User Frequency is now displayed on the graph window.
- The Error Rate Measure frame is added to the configuration
dialogue box. The at +/- % of T. P. is the distance
from the track center in %. Track (Pitch) and Abs
(absolute) location are read-only fields.
