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 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.

The invention is particularly useful for piezoelectric actuators, such as actuators that implement a bimorph piezoelectric crystal structure or a laminate piezoelectric crystal structure, although other actuators may present similar non-linearity issues. In one embodiment, the invention provides a method comprising applying a signal to an actuator of a data storage system, the actuator having a non-linear response, wherein the signal includes a linear drive component and a non-linear adjustment component, and positioning a data storage head with respect to a data storage medium via the actuator.

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： 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 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： A magnetic tape system comprises a magnetic tape, a magnetic head, a set of guides arranged to guide the magnetic tape along a tape path over the magnetic head, a first resistance mechanism, and a second resistance mechanism. The set of guides comprises a first rotatable guide positioned before the magnetic head along the tape path and including a first flyable tape path surface, and a second rotatable guide positioned after the magnetic head along the tape path and including a second flyable tape path surface. The first and second resistance mechanisms resist rotation of the first and seconds guides, respectively.

摘要： In a method and apparatus for detecting leaks in riser and lid assemblies, a difference in pressure between the inside of the riser and cover assembly and the outside is created and monitored to insure that no leaks exist. Preferably, a vacuum is created on the inside of the riser and cover assembly. This vacuum is then monitored for a set period of time to insure that the total change in pressure does not exceed a threshold. In a highly preferred embodiment, an apparatus automatically creates the desired vacuum and then isolates a vacuum gauge to monitor the vacuum in the riser. Method for isolating a leak are also presented in the event that a leak is detected.
