said reflective pad provides a linear reflectance signal over a
range of approximately 0.075 inches;
creating a first erased region on said floppy disk surface
by operating a write element of the magnetic core in an erase
mode while the magnetic core remains in said first radial
position and said floppy disk is rotated through at least part of
one whole rotation of said floppy disk;
moving the magnetic core to a second radial position
neighboring said first radial position on a second revolution of
said floppy disk approximately two mils from said first position
with said voice coil motor wherein said fine position actuator
moves relative to said base carriage;
creating a second erased region longitudinally aligned with
and radially displaced from said first erased region, by
operating said write element in an erase mode while the magnetic
core remains in said second radial position and said floppy disk
is rotated through said revolution of said floppy disk;
moving the magnetic core to a third position on a third
revolution of said floppy disk with said position sensor and said
voice coil motor to position said fine position actuator relative
to said base carriage, wherein said write element of the magnetic
core is radially aligned midway between said first and second
erased regions; and
writing a track of data longitudinally aligned with and
between said first and second erased regions that overwrites a
radial portion of both said first and second erased regions,
wherein a pair of erased blank areas result on either radial side
of said written data track that are each radially narrower than
said written data track and separate said written data track from
any adjacent data tracks.
