“…Head designs 1) and 2) were processed on AlTiC wafers and fabricated into finished heads using standard head assembly and lapping techniques [6], [7]. Attached to the read modules was a six-turn thin-film write head comprised of CoZrTa poles and 0.65-m gap similar to that described in [8]. This write head had a wide track width 36 m to enable write-wide-readnarrow recording measurements.…”

Shielded magnetoresistive (MR) and giant magnetoresistive spin-valve (SV) tape head performance is compared using square-wave recording on metal particle tape. The relatively large tape medium magnetic thickness drives flux levels that overpower sensitive thin MR elements and SV-free layers. Recording data comparing wide track (20 m) dual-stripe MR heads and narrow track (3.5 m) SV heads is shown illustrating SV element saturation at long wavelengths and large reproduce outputs at short wavelengths (7.2 mVp-p at 4000 fr/mm). Measures to counter this observed incompatibility are outlined in terms of media properties, recording method, and SV read-head design.Index Terms-Magnetic recording/reading heads, magnetoresistive (MR) materials and devices, spin-valve (SV) heads, tape recording.

Imaging of nanoscale magnetic textures within extended material systems is of critical importance to both fundamental research and technological applications. While high-resolution magnetic imaging of thin nanoscale samples is well established with electron and soft x-ray microscopy, the extension to micrometer-thick systems currently requires hard x rays, which limits high-resolution imaging to rare-earth magnets. Here, we overcome this limitation by establishing soft x-ray magnetic imaging of micrometer-thick systems using the pre-edge phase x-ray magnetic circular dichroism signal, thus making possible the study of a wide range of magnetic materials. By performing dichroic spectroptychography, we demonstrate high spatial resolution imaging of magnetic samples up to 1.7 μm thick, an order of magnitude higher than conventionally possible with soft x-ray absorption-based techniques. We demonstrate the applicability of the technique by harnessing the pre-edge phase to image thick chiral helimagnets, and naturally occurring magnetite particles, gaining insight into their three-dimensional magnetic configuration. This new regime of magnetic imaging makes possible the study of extended non-rare-earth systems that have until now been inaccessible, including magnetic textures for future spintronic applications, non-rare-earth permanent magnets for energy harvesting, and the magnetic configuration of giant magnetofossils.
