Appeal No. 2001-2402
Application No. 08/422,849
read and write operation, the read transducers are positioned on
the recording head such that one read transducer always tracks a
servo track (specification, page 2). According to Appellant, by
spacing the write and read transducers uniformly but at different
intervals, a read transducer is always indexed over a servo track
and another read transducer is also indexed immediately to the
right or left of other servo tracks (specification, page 4).
Thus, accurate transducer positioning and tracking as well as
maximizing the useable space on the magnetic medium can be
achieved (id.).
Representative independent claims 1 and 16 are reproduced
below:
1. A magnetic recording head, comprising:
a plurality of write transducers configured both for
writing a plurality of servo tracks simultaneously on a
magnetic medium and for writing a plurality of data tracks
on the magnetic medium, said servo tracks and said data
tracks each having substantially the same width; and
a plurality of read transducers configured for tracking
the servo tracks as the write transducers write the data
tracks, wherein the write transducers are equally spaced
cross-track from one another, the read transducers are
equally spaced cross-track from one another, and the cross-
track spacing between said write transducers is different
from the cross-track spacing between said read transducers.
