Patent ID: 6967809

Claim:
A disk drive controlling the position of a read-write head communicatively coupled to a rotating disk surface by a voice coil actuator containing said read-write head, further comprising: means for formatting said disk surface, further comprising, for each of said tracks of said rotating disk surface, and for each of said sectors of said track: means for calculating a starting radius and an ending radius for said sector within said track; wherein said starting radius differs significantly from said ending radius; and means for positioning said read-write head by linearly varying said read-write head position from said starting radius to said ending radius through control of said voice coil actuator; and means for writing said information to said sector of said track while performing the step positioning said read-write head from said starting radius to said ending radius; wherein said rotating disk surface includes an ordered sequence of said tracks, and each of said tracks of said rotating disk surface includes an ordered sequence of said sectors; wherein any of said ordered sequences possesses a first member, and a last member; wherein for any of said ordered sequences, any member of said ordered sequence which is not the last member possesses a successor member; wherein for each of said tracks of said rotating disk surface having a successor track, said ending radius of said last member of said sector sequence for said track is very close to said starting radius of said first sector sequence member of said successor track.
