TEMPLATED GRANULAR MAGNETIC RECORDING MEDIA

摘要

A system and method for recording data to a perpendicular magnetic recording media having a highly ordered granular structure. The method includes the synchronization of write frequency and write phase to the granular structure of the magnetic media optimize performance of the magnetic data recording system by minimizing bit error rate.

1. A method for magnetic data recording, comprising:
providing a magnetic media configured for perpendicular magnetic data recording and having an ordered granular structure; writing an un-synchronized bootstrap servo to the magnetic media; creating a frequency map; creating a phase map; writing a synchronized servo; refining the frequency map; and refining the phase map; wherein the steps of refining the frequency map and refining the phase map are repeated until a change in frequency and a change in phase are no greater than a predetermined allowable value.
