Implementations described and claimed herein includes a storage device comprising a transducer heat including at least one pair of read/write elements and a heat shaped to thermally protrude regions of the transducer head including the read/write elements. According to one implementation, the heat element includes at least one conductive portion of locally decreased resistance proximal to and between the pair of read/write elements to direct the thermally protruded close point away from a midpoint between the read/write elements.

An apparatus includes an array of write transducers. Each write transducer includes a lower yoke, a lower write pole piece comprising a lower base layer in magnetic communication with the lower yoke and a lower high moment layer above the lower base layer. Each write transducer includes a write gap above the lower write pole piece and an upper write pole piece above the write gap. The upper write pole piece includes an upper high moment layer above the write gap and an upper base layer above the upper high moment layer. Each write transducer includes an upper yoke above the upper base layer. A media facing side of the lower pole piece and at least a portion of a media facing side of the upper pole piece extend along a plane and the remainder of the media facing side of the upper pole piece is recessed from the plane.

An apparatus according to one approach includes an array of skew detection transducers. An array of write transducers is spaced from the array of skew detection transducers along an intended direction of tape travel thereacross. An array of read transducers is aligned with the array of write transducers in the intended direction of tape travel. The apparatus also includes a first actuator configured to operatively exert a force on the array of skew detection transducers for orienting a longitudinal axis of the array of skew detection transducers substantially orthogonal to the actual direction of tape travel across the array of skew detection transducers. A magnetic recording medium according to one approach includes a magnetic recording tape having a longitudinal axis extending between distal ends thereof, the magnetic recording tape having vertical bars written in servo-skew patterns thereof, the vertical bars being oriented perpendicular to the longitudinal axis of the tape.

Aspects of the present disclosure generally relate to a base and related methods for write and read heads. In one example, the base and related methods are used as part of a magnetic storage device, for example a magnetic media drive such as a hard disk drive (HDD) or a magnetic tape drive (e.g., a tape embedded drive). The base includes one or more base bodies formed of a ceramic material. Each base body includes an inward surface, an outward surface opposing the inward surface, a lower surface, and an angled upper surface disposed above the lower surface. Each base body includes a vertical opening extending between the upper surface and the lower surface. In one example, two base bodies are bonded together. In one example, the two base bodies combine to form a single base body of the base that is monolithic and unitary.

An apparatus, in accordance with one aspect of the present invention, includes an inner array of data transducers on a module, the data transducers of the inner array being aligned along a common axis that extends between distal ends of the module. Two outer arrays of data transducers are positioned to sandwich the inner array therebetween. Inner servo readers are positioned between the inner array and the outer arrays. Outer servo readers are positioned toward outer ends of the outer arrays. Widths of at least some of the outermost data transducers in the inner array are less than widths of at least some of the innermost data transducers in the inner array.

A self servo-write process in performed on two or more recording surfaces simultaneously. In a dual-stage servo system, a first fine positioning servo system that includes a first microactuator independently controls the position of a first read/write head over a first recording surface of a hard disk drive, while a second fine positioning servo system that includes a second microactuator independently controls the position of a second read/write head over a second recording surface of the hard disk drive.

The present disclosure generally relates to a Wheatstone bridge that has four resistors. Each resistor includes a plurality of tunneling magnetoresistance (TMR) structures. Two resistors have identical TMR structures. The remaining two resistors also have identical TMR structures, though the TMR structures are different from the other two resistors. Additionally, the two resistors that have identical TMR structures each have an additional non-TMR resistor as compared to the remaining two resistors that have identical TMR structures. Therefore, the working bias field for the Wheatstone bridge is non-zero.

Embodiments are disclosed for a method. The method includes determining a reference plane for a tape drive read-write array. The tape drive read-write array includes a first array element, a predetermined array element, and a last array element. Further, determining the reference plane is based on a first array position of the first array element and a last array position of the last array element. The method also includes capturing a position of a predetermined array element using an imaging device. The method further includes determining a deviation of the captured position from the reference plane. Additionally, the method includes generating a plot of an in-plane bow based on the deviation.
