Abstract: 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.

Abstract translation: 公开了一种新的磁记录介质，其中多个磁数据记录层和导航层彼此分开。 通过解耦导航和数据层，可以将数据写入数据层，而不需要沿着伺服磁道对准写入的数据。 因此，可以将数据层配置为高记录密度。 有利的是，磁数据层中的缺陷也可以通过使用自适应纠错方案进行补偿，所述自适应纠错方案基于记录介质的本地质量在写入/读取期间改变数据的编码/解码。
