The masks were a portion of the disk placed one half line width apart on the disk, such that one or the other went black at half line intervals. This allows you to have a large sensing area, and average out disk image errors. This doesn't account for the index though. I guess you would need a separate short lined section and another mask. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
