Patent ID: 7417813

Claim:
A data recording apparatus, comprising: a rotatable surface having a generally circular first data track with a data track start location, the first data track having a first portion starting at approximately the data track start location; a transducer movable along a path substantially over the first data track, the path including: a path start location that corresponds with the data track start location; a first segment of the path corresponding to the first portion of the first data track; a path end location located such that one iteration of following the path passes over the first segment twice; wherein the transducer writes first particular data to the first segment while writing from the path start location to the path end location during a continuous first writing of the path; and wherein the transducer selectively follows the path and selectively writes the first particular data to the first segment a second time during the continuous first writing of the path when the path corresponds to the first data track having a reduced reliability access.
