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 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： Techniques are described for reselling and/or refurbishing data tape media. The techniques may involve determining life information associated with a data tape medium and reselling the data tape medium when a remaining life of the data tape medium is larger than a pre-defined threshold. In this manner, the quality of resold magnetic tape can be improved, and the media can possibly marketed or warranted to the buyer based on the remaining life. In addition, refurbishing techniques are described that include degaussing of servo written data tape media, followed by the creation of new servo patterns on the degaussed media.

摘要： The invention is directed to a data storage medium that includes a plurality of servo bands distributed across the data storage medium and a plurality of data tracks positioned between each of the plurality of distributed servo bands. The data storage medium comprises a servo band pitch of less than 200 micrometers. The large number of servo bands distributed across the data storage medium with a relatively small servo band pitch reduces the influence of media dimensional instability. In this way, the invention may substantially increase data read head positioning accuracy, especially in the case of narrow track widths. A read head array arranged in a two-dimensional matrix that includes a first servo read head, a second servo read head, and a plurality of data read heads positioned between the first and second servo read heads may be applied to a data storage medium as described herein.

摘要： The invention is directed to a servo frame that includes servo windows written with different frequencies to provide redundant positioning information. The servo frame includes a set of first servo windows recorded at a first frequency and a set of second servo windows recorded at a second frequency arranged in a checkerboard-like pattern. The different frequencies of the servo windows allow the servo frame to achieve improved positioning information redundancy. A servo track may include a plurality of the servo frames described herein to accurately position data read/write heads adjacent corresponding data tracks. The redundancy built into each of the servo frames substantially minimizes errors in the positioning information.

摘要： In general, the invention provides a magnetic head device and linear tape drive that widen the high frequency side of the servo range. In particular, the invention provides a magnetic head device comprising a magnetic head chip with multiple magnetic elements arranged for recording or playback of multiple tracks and a fine positioning structure that uses a bimodal construction that may widen the high frequency side of the servo range by increasing the resonant frequency of the magnetic head chip including the tracking structure and lowering the Q value of the resonance point. In addition, the invention includes a damping structure suitable for the fine positioning structure that improves high speed response by widening the range in which the magnetic head device can be used for a servo. The magnetic head device may use a linear tape drive method.

摘要： In general, the invention provides a magnetic head device and linear tape drive that increase the resonant frequency and the range of a servo system. In particular, the invention provides a magnetic head device comprising a magnetic head chip with multiple magnetic head elements that is a structural part of the fine positioning system which allows the magnetic head elements follow the data tracks on the linear magnetic tape. Consequently, weight is reduced thereby increasing the resonant frequency and servo bandwidth. In another embodiment, the invention provides a magnetic head comprising bimodal actuators that are formed into an S shape and displaced by applying voltage where the polarization direction is opposite from one end to the other. In particular, the head chip may remain stable and may be driven dynamically thereby allowing the mechanical resonance of the bimodal actuator (including the head chip) to increase to 1 kHz or higher.
