OFFSET CORRECTION VALUES ON A DATA STORAGE MEDIA

摘要

A memory system includes a storage medium having tracks arranged on the storage medium. The tracks include data track portions configured to store data. The tracks have a data track width and offset correction portions having a width that is greater than the data track width of the associated data track. Each offset correction portion stores one or both of positional offset correction values and timing offset correction values. The positional offset correction values are configured to correct for errors that occur in cross track positioning relative to the medium and the timing offset correction values are configured to correct for errors that occur in down track timing relative to the medium.

1. An apparatus, comprising:
a storage medium having tracks arranged on the storage medium the tracks including:
data track portions configured to store data and having a data track width; andoffset correction portions having a width in a cross-track direction that is greater than the data track width in the cross-track direction of an associated data track, each offset correction portion storing one or both of positional offset correction values and timing offset correction values, the positional offset correction values configured to correct for errors that occur in cross track positioning relative to the medium and the timing offset correction values configured to correct for errors that occur in down track timing relative to the medium.
