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： 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 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： 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： The invention provides a read-while-write recording system for a linear data storage medium, such as magnetic tape or other data storage medium in which data is stored on parallel data tracks that extend along a length of the medium. The invention makes use of separate sliders for the read and write elements, and separate actuators to control the positioning of the sliders. Each of the sliders may also include servo elements to read servo marks. In this manner, the write elements of a first slider can be positioned independently from the read elements of a second slider in order to achieve improved head positioning with respect to data tracks on the linear data storage medium.

摘要： The invention proposes the use of a piezoelectric crystal element as an actuator for data storage systems. In particular, the piezoelectric crystal element mechanically positions a head with respect to a data storage medium. More specifically, the invention may use a piezoelectric laminate crystal structure as a fine positioning actuator in a magnetic tape system in order to precisely position one or more heads with respect to tracks of the magnetic tape. Furthermore, in order to address hysteresis in the piezoelectric crystal element, the invention proposes the introduction of a high frequency periodic signal as part of the input to the piezoelectric crystal element.

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.

摘要： The improved process and apparatus for the restoration of seagrass includes a biodegradable bag or sack, referred to as a sediment tube, that is filled with sand and placed in a prop scar or blow hole. The sediment tube corrects many issues created a prop scar or blowhole: (1) the trench or hole is filled, restoring the elevation of the scar to the surround grade of the seagrass; (2) the sediment tubes stabilize the scar, preventing further erosion of the sand by the flow of water; (3) the sediment tube optionally includes fine-grained sediments that promote seagrass growth and recovery; and (4) the sediment tube includes fertilizer and/or other chemical or minerals that encourage growth.
