WITE32 Release Notes Version 3.11
There are two frames in the dialog box – the Erase Parameters frame and the Band Erase Parameters frame.
The Erase Parameters frame allows you to define the erase configuration.
The Iterations text box Defines the number of repetitions for each erase operation at each
offset
The Mode option buttons Defines the erase modes:
• Positive DC – the DC erase operation using the positive write
current for one revolution.
• Negative DC – the DC erase operation using the negative
write current for one revolution.
• Positive DC / Negative DC – the DC erase operation using
the positive write current for the first revolution, followed by
the DC erase operation using the negative write current for
the second revolution.
• Negative DC / Positive DC – the DC erase operation using
the negative write current for the first revolution, followed by
the DC erase operation using the positive write current for
the second revolution.
• AC – the AC erase operation for one revolution with the
frequency defined in the Frequency text box.
The Frequency text box Defines the frequency for the AC erase operation, in MFlux/s.
The Write Current text boxes Define the write current values (in mA) used in the erase operation.
You can configure individual write current for the first and the second
revolution.
The Use System check boxes If the check box is checked, the Write Current text box value for the
corresponding revolution is ignored. The current system write current
is used instead.
The Band Erase Parameters frame allows you to define the area around the current track for the band erase operation.
The From text box Defines the starting offset position for the band erase operation,
in µInch.
The To text box Defines the ending offset position for the band erase operation,
in µInch.
The Step text box Defines the offset step size for each erase operation, in µInch.
The Interleave Band Erase
check box
If it is checked, the Mode option is ignored. The band erase operation
is done in the following way:
1. Erase using the positive write current at the first offset
position.
2. Erase using the negative write current at the second
offset position.
3. Erase using the positive write current at the third offset
position, etc.
Note: The band erase area is specified in terms of the head writer offset (in µInch) in respect to the center of the track.
All System Erase and System Band Erase parameters are zone/setup dependent, you can double-click on the
parameter label to specify the value of the parameter for each zone and setup.
