MAGNETIC RECORDING MEDIUM

摘要

A novel magnetic recording medium is disclosed in which a plurality of magnetic data recording layers and navigation layers are separate from one another. By decoupling the navigation and data layers, data may be written to data layers without the need to align the written data along servo tracks. Thus, the data layers may be configured for high recording density. Beneficially, imperfections within the magnetic data layers may also be compensated for by the use of adaptive error correction schemes which vary the encoding/decoding of data during writing/reading based upon the local quality of the recording media.
