摘要： The invention provides a system comprising a non-linear array of magnetoresistive (MR) heads arranged in a two-dimensional matrix for reading information stored on magnetic media. The non-linear array of MR heads may comprise a planar array formed by a plurality of linear arrays of MR heads stacked to define a plurality of layers. Each of the linear arrays may share at least one shield element with another linear array of the non-linear array. In general, each layer is offset by one written track pitch and the number of layers of the invention is equal to the number of written track pitches in a channel pitch. The invention can also be used in a system for reading and writing information to magnetic media at improved track pitches relative to conventional read/write systems.

摘要： Servopositioning data is written onto a linear recording medium such that a position error signal (PES) is intentionally created. The signal substantially resembles a conventional time based servo pattern, but is insensitive to transverse position. In a preferred embodiment, the signal at a zero-azimuth, i.e., an angle sufficiently small in value such that there is no significant PES signal associated with the transverse motion.
摘要翻译：伺服定位数据被写入线性记录介质，从而有意创建位置误差信号（PES）。信号基本上类似于传统的基于时间的伺服模式，但对横向位置不敏感。在优选实施例中，在零方位角处的信号，即具有足够小的值的角度使得不存在与横向运动相关联的显着PES信号。

摘要： A servo pattern is described that facilitates high resolution and wide dynamic range to accurately pinpoint servo track centerlines on a magnetic tape. The servo pattern provides both absolute positioning information over an entire servo band and absolute positioning information relative to the centerline of each servo track included in the servo band. Therefore, the servo pattern includes implicit servo track identification in a single servo band, eliminating the need for conventional track identification marks. In other words, the servo pattern, itself, can distinguish one servo track from another servo track in the single servo band as well as provide highly accurate positioning information relative to each of the servo track centerlines.

摘要： In general, the invention relates to a data storage tape including servo information on both sides of the tape. Techniques for writing servo information to both sides of the data storage tape are also described. For example, a mechanical arrangement of two servo write heads positioned with respect to the data storage tape can enable two-sided servo recording. In addition, a single servo write head may be used to write servo information to both sides of the data storage tape with the aid of a flux conductor. In that case, the magnetic field of the servo write head passes through the data storage tape to record servo information on both sides of the tape.

摘要： The invention is directed to patterns of amplitude-based servo windows that eliminate the need for conventional track identification marks, and various servo writing devices and head configurations that facilitate creation of such servo patterns. The patterns of servo windows may also eliminate the need for conventional synchronization marks. In accordance with the invention, the patterns of servo windows, themselves, can distinguish one track from another track in one or more servo bands and inherently provide synchronization without the need for synchronization marks between servo frames. In other words, the same amplitude-based servo windows that define the centerlines of the tracks can be arranged to provide track identification information and possibly inherent synchronization information.
摘要翻译：本发明涉及基于幅度的伺服窗口的图案，其消除了对常规轨道识别标记的需要，以及有助于创建这种伺服模式的各种伺服写入设备和头部配置。伺服窗口的图案也可以消除对常规同步标记的需要。根据本发明，伺服窗口本身的图案可以将一个轨道与一个或多个伺服带中的另一个轨迹区分开，并固有地提供同步而不需要伺服帧之间的同步标记。换句话说，定义轨道的中心线的相同基于幅度的伺服窗口可以被布置成提供轨道识别信息和可能的固有同步信息。

摘要： The invention is directed to a magnetic storage medium recorded with an amplitude-based servo pattern in which one or more first servo windows positioned above a centerline of a servo track have a different width than one or more second servo windows positioned below the centerline. The first servo windows may be larger or smaller than the second servo windows. In either case, by detecting the widths of the servo windows and detecting signal amplitude as a servo head passes relative to the servo track, servo tracking can be achieved without the use or need for additional synchronization marks in the servo pattern.
