Patent ID: 8922926

Claim:
A recording medium, comprising: a dedicated servo layer for providing continuous magnetic servo information on a disk, a data recording layer configured to record magnetic data therein, wherein the dedicated servo layer comprises a plurality of tracks, wherein a first track of the plurality of tracks comprises a first magnetic preamble signal, wherein the first track further comprises a first magnetic servo burst signal of a first frequency, wherein a second track of the plurality of tracks comprises a second magnetic preamble signal, wherein the second track further comprises a second magnetic servo burst signal of a second frequency which is different than the first frequency, wherein the first magnetic servo burst signal and the second magnetic servo burst signal comprise a plurality of common transitions, wherein the common transitions are provided at a pre-determined frequency, wherein the magnetic servo information is provided on the servo layer distinct from the data recording layer to provide continuous location detection, and wherein the first frequency and the second frequency have a ratio of n:m with integer numbers n and m or have a ratio of n+1:n with an integer number n.
