In an arcuate scanner, a read head senses passage over a reference stripe recorded on a moving recording tape. Detection and logic circuitry respond to the read head signal to detect the reference stripe and determine an angular position of the read head with respect to an index associated with the arcuate scanner head assembly. Timing operations of the arcuate scanner and alignment of the arcuate scanner head assembly with regard to an information recording region on the tape are controlled in reference to the detection of the reference stripe.

Apparatuses are configured to addresses tape dimensional stability (TDS) via small rotations about the quasi-static tilt angle and read and / or write data in non-legacy formats. Products such as tape media products are also presented.

The present invention, in some embodiments, relates to magnetic heads having modules with arrays of transducers able to read and / or write while the arrays are positioned at different angles relative to a magnetic medium, thereby enabling reading and / or writing in more than one data storage format. An apparatus according to one embodiment includes a first module having a first array of N+1 transducers, and a second module having a second array of N+1 transducers. Axes of the arrays are oriented about parallel to each other. N of the N+1 transducers of a first array of a first of the modules are about aligned with N of the N+1 transducers of a second array of a second of the modules when the axes of the arrays are tilted at a first angle greater than about 0.1° relative to a line oriented perpendicular to an intended direction of tape travel thereacross.

In a helical scan type magnetic tape recording apparatus, one thin film multi-recording head is mounted on a rotary drum, wherein the multi-recording head includes N recording heads for recording N recording tracks at a predetermined track angle on a magnetic tape by one rotation of the rotary drum to perform recording for forming continuous recording tracks having the same track pitches, by determining rotary drum rotation and a tape speed in accordance with equation V1=Tp·N·(RPS) / sin θ, such that (N−1) recording tracks having the same track pitches narrower than the head width and one recording track having a wider track width than that are formed by a first rotation of the drum, then by a second rotation, a preceding recording head overwrites the recording track having the wider track width to form a recording track having a track width equal to the track width of the recording track.

A head stack assembly (HAS) of a hard disk drive (HDD) includes a swing arm, a connection plate integral with a terminal end of the swing arm, a head slider including a magnetic head for reading / writing data from / onto a disk, and a suspension that is attached to the connection plate, supports the head slider, and has characteristics which minimize the degree to which the magnetic head will run off-track due to vibrations induced in the HDD. The suspension includes two connecting parts having upper surfaces at which the suspension is attached to the connection plate. In the HDD, the upper surface of the connecting part positioned closest to the center of the disk center lies in a plane beneath the plane in which the upper surface of the other connecting part lies. Also, that half of the suspension which is disposed to one side of the central longitudinal axis of the HSA and is located remotely from the center of the disk in the HDD is stiffer than the other half of the suspension which is proximal the center of the disk. To this end, the suspension includes at least one side-rail that renders the suspension asymmetrical.

An apparatus according to one embodiment includes a head having at least two modules, each having an array of transducers. Axes of the arrays are about parallel and are spaced from one another in an intended direction of tape travel thereacross. The array of a first of the modules is offset from the array of a second of the modules in a first direction parallel to the axis of the array of the second module such that the transducers of the first module and the transducers of the second module are positioned to fill a contiguous data band with written tracks in multiple passes. All of the transducers of the first module are positioned on a first side of an imaginary line oriented in the intended direction of tape travel, and all of the transducers of the second module are positioned on a second side of the imaginary line.
