Provided are a magnetic tape head, a magnetic tape drive, and a computational device in which the magnetic tape head is comprised of a plurality of elements, wherein a pitch between adjacent elements of the plurality of elements is not identical. Selected elements of the plurality of elements that are shifted from a nominal position are selected in a symmetrical manner in the plurality of elements. A total of shifts of the elements of the plurality of elements that are shifted add up to a desired total shift to realign a plurality of modules, such that the median head span of each module type match as closely as possible to a desired value of a head span for all module types.

The magnetic tape includes: a non-magnetic support; and a magnetic layer containing a ferromagnetic powder, and a magnetic tape cartridge and a magnetic tape apparatus include the magnetic tape. In a binarized image of a secondary electron image obtained by imaging a surface of the magnetic layer with a scanning electron microscope at an acceleration voltage of 5 kV, the number of bright regions having an equivalent circle diameter of 60 nm or more and less than 120 nm is 8000 or more and 30000 or less. Standard deviation σ of the number of the bright regions in a width direction of the surface of the magnetic layer is 2000 or less.

Provided are a magnetic tape head, a magnetic tape drive, and a computational device in which the magnetic tape head is comprised of a plurality of elements, wherein a pitch between adjacent elements of the plurality of elements is not identical.

A magnetic tape device includes: a magnetic head; a head actuator that holds the magnetic head; and a tape lifting mechanism including a lifter arm. The lifter arm comes into contact with the magnetic tape to separate a magnetic tape from the magnetic head. The tape lifting mechanism moves the lifter arm in a push-out direction in conjunction with the head actuator moving in a first direction. The tape lifting mechanism moves the lifter arm in a retreating direction in conjunction with the head actuator moving in a second direction. The lifter arm pushes out the magnetic tape to separate the magnetic tape from the magnetic head, in response to the lifter arm moving in the push-out direction. The lifter arm separates from the magnetic tape to bring the magnetic tape into contact with the magnetic head, in response to the lifter arm moving in the retreating direction.

A storage device comprises tape reel(s) holding tape media for storing data, a head assembly, motor(s) configured to actuate the head assembly, a sealed casing, and a printed circuit board assembly (PCBA) configured to control operations of the motor(s). The head assembly comprises a support structure, a head bar with read head(s) and write head(s), and a suspension system connecting the head bar to the support structure. The sealed casing encloses in its interior the tape reel(s), the head assembly, and the motor(s). Meanwhile, the PCBA is mounted on an external surface of the casing.

A recording and reproducing apparatus includes: a magnetic head in which a servo band having a servo pattern and a data band having data tracks are alternately arranged along a width direction, the magnetic head including a recording and reproducing element that records or reproduces data with respect to the data track, and at least two servo reproducing elements that read servo patterns adjacent to each other in the width direction of the magnetic tape; a selection unit that selects a servo reproducing element from the servo reproducing elements according to a position of the data track, as a target of recording or reproducing of data in the data band, along the width direction; and a controller that controls positioning of the magnetic head along the width direction by using a result of reading of the servo patterns by the servo reproducing element selected by the selection unit.

The present disclosure generally relates to a head assembly of a data storage device. The data storage device may include magnetic media embedded in the device or magnetic media from an insertable cassette or cartridge (e.g., in an LTO drive), where the magnetic head assembly reads from and writes to the magnetic media. During drive operation, the magnetic media moves across the magnetic head assembly. The magnetic head assembly is spaced a distance from the magnetic media such that non-contact recording occurs between the magnetic head assembly and the magnetic media. The magnetic media is supported by either a back plate or an air film generated by one or more fillet edges of the back plate and the velocity of the magnetic media as the magnetic media moves across the magnetic head assembly.

The present disclosure generally relates to a voice coil motor (VCM) yoke assembly mounted to an actuator block for a data storage device. One or more fastening mechanisms couple the VCM assembly to the actuator block. The fastening mechanisms are coupled to the VCM assembly by one or more soft mounts. The one or more soft mounts reduce undesirable movement of the magnetic recording head by spacing the VCM assembly from the actuator block, yet still ensuring the VCM assembly is properly coupled to the actuator block.

The present disclosure generally relates to a head positioning assembly in a tape embedded drive. The tape embedded drive has two reels as well as four guide rollers. The reels and guide rollers are arranged within the tape embedded drive so as to position the head positioning assembly as close to the center of the tape embedded drive as possible. In so doing, the reels, guide rollers, and head assembly are more stable which reduces or even eliminates shock and vibration to the tape embedded drive.

The present invention relates to the field of tape drives, tape transport, tape heads and tape head suspension. More particularly, the present invention is related to magnetic tape data storage and tape recorders that include components designed to minimize or eliminate head-to-tape contact to reduce or eliminate wear and contamination of tape drive heads. Methods and apparatus of the present invention may dynamically control the head-to-media spacing by moving locations of magnetic heads relative to a tape. Such apparatus may include components designed to minimize magnetic spacing. This may be accomplished using actuators that move the magnetic heads, that move the tape, or that move both the magnetic heads and the tape. This may include supporting a back surface of the tape. Alternatively, or additionally, the movement of the tape past the magnetic heads may be performed using mechanisms that contact and drive the back surface of the tape.
