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 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. Accordingly, the invention can facilitate increased storage densities on magnetic media and may have advantages in terms of quality of readout and ease of manufacture relative to magneto-optical read heads or other read heads.

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.
摘要翻译：描述了一种有助于高分辨率和宽动态范围的伺服模式，以精确地精确定位磁带上的伺服轨道中心线。伺服模式提供整个伺服带上的绝对定位信息和相对于包括在伺服带中的每个伺服轨道的中心线的绝对定位信息。因此，伺服模式包括在单个伺服频带中的隐式伺服磁道识别，消除了对常规磁道识别标记的需要。换句话说，伺服模式本身可以区分单个伺服频带中的一个伺服磁道与另一个伺服磁道，并且相对于每个伺服磁道中心线提供高精度的定位信息。

摘要： The invention is directed to arrangements of tapered data storage tape guides which can improve the guiding of data storage tape. Tapered data storage tape guides having specific sizes relative to the data storage tape are also disclosed. The tapered data storage tape guides and arrangements of tapered guides can improve the ability to properly guide the data storage tape, e.g., during media fabrication, servo recording or readout, data recording or data readout. In one embodiment, a data storage tape guiding system may include a first tapered guide and a second tapered guide. The taper in the first guide can be opposite the taper in the second guide such that the data storage tape is forced against an upper flange of the first guide and forced against a lower flange of the second guide, or vice versa.

摘要： The invention provides a tape drive comprising a head mounted on a turntable. The turntable rotates to allow the head to access first and second sides of a data storage tape. Techniques for accessing the first and second sides may include rotating the turntable to position the head in first and second positions. In addition, the techniques may further include raising and lowering the turntable relative to the data storage tape in order to facilitate access to both sides of the data storage tape without requiring the data storage tape to be unspooled and re-spooled.

摘要： In an embodiment, a data storage tape includes a first side including recorded data and a second side including recorded error correcting code data for the recorded data on the first side. In another embodiment, a data storage tape comprises a first side including recorded data and a second side including a copy of the recorded data. Embodiments of the invention may distribute related data across both sides of a data storage tape and as a result may reduce the probability that a location-dependent error in the data storage tape will result in irretrievable data loss. Embodiments of the invention may be particularly useful for systems that can simultaneously retrieve or record data on both sides of a dual-sided data storage tape.
摘要翻译：在一个实施例中，数据存储带包括包括记录数据的第一侧和包括第一侧上记录数据的记录纠错码数据的第二侧。在另一个实施例中，数据存储带包括包括记录数据的第一侧和包括记录数据的副本的第二侧。本发明的实施例可以在数据存储磁带的两侧分布相关数据，并且因此可能降低数据存储磁带中与位置相关的错误将导致不可恢复的数据丢失的可能性。本发明的实施例对于能够同时在双面数据存储带的两侧检索或记录数据的系统可能特别有用。

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.
