All discussion of features and bugs in this document uses WITE version 1.4 as a baseline for comparison. For information about features and modifications prior to 1.4, please refer to the WITE user’s manual and to the release notes for previous revisions of WITE. New Features in WITE 1.41New track profile result[Top of this page]In WITE 1.4, the track profile test was enhanced to measure the write width, read width and read-to-write offset. WITE 1.41 adds a new result. TPWrRdDelta is the difference between the write and read widths reported separately. This result is useful for grading the relative widths of the read and write gaps for production testing. No changes have been made to the track profile interface. This result is not displayed in the printed track profile plot, but is available among the results and can be graded. Support for new PRML chips and head stacks[Top of this page]The following new PRML chip is supported:
The following new head stacks are supported:
Bugs Fixed in WITE 1.41[Top of this page]When WITE 1.4 was used with a new TSA-suspension cartridge, problems reading the EEPROMS would sometimes cause error messages saying "Error 1044: no head amplifier connected" or "Error 1028: EEPROM no acknowledge." WITE 1.41 correctly reads the EEPROMS and does not exhibit this problem. Immediately after running a production sequence which included scanning, an attempt to delete a zone sometimes resulted in an "Operation not supported in transactions" error message. WITE 1.41 does not trigger this error message. A "Cannot sort zones" error message appeared intermittently when zone execution order was changed in the production test. WITE 1.41 does not encounter this problem. Known bugs in WITE 1.41[Top of this page]Some bugs were found too late to be fixed for the 1.41 release and will be fixed in a later release. This section contains all known bugs that you are likely to encounter. A bug’s presence here means that we are aware of the problem and actively working to solve it. If you encounter a problem not on this list, please report it to Guzik customer support. The "retest with next setup" option in the "Production | Grd/Norm" menu does not register results to the database after the first setup. It should not be used. Some DOS applications interfere with communication with Guzik hardware and can result in unstable test results. Please exit all DOS applications before running WITE. |
