A magnetic recording system utilizing a plurality of surfaces on a magnetic
recording disk with recording zone boundaries established on the
respective surfaces of the disk based on performance characteristics of
the read/write transducer associated with the surface. The performance of
the read/write transducer from the aspects of the width of the track
written by the transducers as well as the recording performance at the
expected recording frequency, are both utilized in building disk drives.
Since the zone boundaries are established uniquely for the performance of
each transducer, rather than by defining the boundaries of all zones for
all surface in advance based on assumed performance characteristics of the
heads, the zone boundaries on one surface of the disk will not necessarily
align with the zone boundaries on another surface of the disk. Similarly,
when a plurality of disks are utilized, the zone boundaries will not
necessarily be aligned. Improved utilization of the available stroke on
the disk drive permits further improvement in recording density. A
magnetic recording system utilizing track pitch based on a track width
characteristic of the read/write transducer used in the system.
