摘要： A system for transferring information to and from a magnetic disk is disclosed wherein the information may be encoded on a data track in a large number of polarization orientations in comparison to conventional bidirectional recording schemes. In one embodiment of the present invention, it is contemplated that a single segment may be polarized in eight different orientations, each of which being distinguishable from each other by a read/write head. Polarization of a segment in one of eight different orientations significantly increases the amount of information which can be stored in any given segment relative to conventional systems which are polarized in only one of two orientations. Thus, the amount of information which may be stored on a disk may be increased without having to alter the linear or radial density of the disk.
摘要翻译：公开了一种用于向磁盘传送信息的系统，其中与传统的双向记录方案相比，信息可以以大量极化取向在数据磁道上进行编码。在本发明的一个实施例中，可以设想单个片段可以以八个不同的取向极化，每个方向通过读/写头彼此区分开。在八个不同取向中的一个中，段的极化显着地增加了可以存储在任何给定段中的信息量，相对于仅在两个取向中的一个方向上被极化的常规系统。因此，可以增加可以存储在盘上的信息量，而不必改变盘的线性或径向密度。

摘要： Storage architecture for bit patterned media uses both erase band and shingled magnetic recording. A hard disk drive may comprise a disk having bit patterned media with a plurality of data tracks arrayed in architecture pages having at least one of erase band mode (EBM), shingled mode (SM) and unallocated space. An actuator has a head for writing data to the data tracks of the bit patterned media. A control system monitors, reallocates and reconfigures the architecture pages from EBM, SM or unallocated space to a different one of EBM, SM or unallocated space to enhance performance of the hard disk drive.

摘要： The present invention generally relates to a magnetic recording system that utilizes perpendicular exchange spring media and ring heads. The write field of ring heads does not experience a strong loss as compared to pole heads because the pole can be kept long in the direction perpendicular to the recording medium and thus does not result in unfavorable write field scaling.
摘要翻译：本发明一般涉及利用垂直交换弹簧介质和环形磁头的磁记录系统。与磁头相比，环形磁头的写入场不会发生强大的损耗，因为磁极可以在与记录介质垂直的方向上保持很长的时间，因此不会导致不利的写入场缩放。

摘要： High bit density, longitudinal and/or perpendicular magnetic recording media that are substantially free of Barkhausen noise are fabricated by utilizing magnetically soft, superparamagnetic underlayers which are compatible with the grain structure of the magnetic recording layer and serve to guide magnetic flux through the magnetic layer. An exchange de-coupling layer is positioned between the superpararnagnetic underlayer and the magnetic layer for prevention of direct coupling of the grains of each the layers.
