Drive:  ___   Side:  ___

     I.   Radial test:   Each sector is offset more from the center
                         of the track than the last.  The test indicates
                         how far the drive can go before it gets
                         read errors.  A head which is centered correctly
                         will read approximately the same number of
                         offsets away from the spindle as toward.

          A.  Track  0:       ____                   ____             ___
          B.  Track  5:       ____                   ____             ___
          C.  Track 16:       ____                   ____             ___
          D.  Track 19:       ____                   ____             ___
          E.  Track 30:       ____                   ____             ___
          F.  Track 39:       ____                   ____             ___

    II.   Azimuth test:  Each sector has data which is tilted more
                         away from being perpendicular to a tangent
                         drawn to the track.  Bad reads indicate
                         the head is probably dirty or noise is
                         present in the computer.  The absolute value
                         of the displayed number will be 42 (meaning
                         an azimuth angle of 42 minutes) if all of
                         the tests succeeded.

          minus ____ minutes,   plus ____ minutes

   III.   Centering test:     same offset toward spindle as away from
                              spindle, and offset doesn't change.
                              Tests the centering of the head
                              in the track.

          A.  Track 21:  OK ___  fatal error ___  re-clamp disk ___
          B.  Track 24:  OK ___  fatal error ___  re-clamp disk ___
          C.  Track 27:  OK ___  fatal error ___  re-clamp disk ___

    IV.   Spindle speed:      Should be as close to 300 RPM as
                              possible.  Fluctuation might be caused
                              by drag or servo problems.  Allowable
                              error is +/- 1.5 percent.

          approx. _________ revs. per min.
