Advanced Soft Magnetic Materials for Magnetic Recording Heads and Integrated Inductors
High performance magnetic heads, inductors and transformers, indispensable to information technology encompassing from information storage, portable power delivery, to wireless communication, require soft magnetic films with low coercivities, high permeability, and large ferromagnetic resonance frequencies. The Fe-Co-N-based films have a ferromagnetic resonance frequency of >1 GHz at zerobias f...
متن کاملNew recording materials for holography
Some of the alternative silver halide materials that can be considered to replace the previous Agfa Holotest materials are discussed. The characteristics of Slavich and HRT materials are examined, including the special aspects of recording and processing ultrahigh-resolution silver halide materials. These materials can offer a significant improvement in product quality. The sensitivity is lower...
متن کاملNew recording materials for the holographic industry
This paper describes a new class of recording materials for volume holographic applications suitable to meet commercial manufacturing needs. These next-generation holographic photopolymers have the ability to satisfy the unmet demand for color and depth tuning that is only possible with volume holograms. Unlike earlier holographic photopolymers, these new materials offer the advantages of no ch...
متن کاملRemanent magnetic measurements on perpendicular recording materials with compensation for demagnetizing fields
Existing techniques for characterization of longitudinal recording media using remanence measurements are extended to perpendicular media, in particular to Alumite, and correction for demagnetizing fields is taken into account. It is found that these techniques have limited value because of the sensitivity of the analysis to the correction factor used. Measurement of the recoil lines is investi...
متن کاملMagnetic sound recording
The first complete magnetic recorder (wire on a drum) was constructed in 1898 by Poulsen (Denmark). In 1938 the first recorders using plastic tape with an iron oxide layer were used. Since then, magnetic sound recording has become the most popular way of storing broadcast programmes for transmission at any time. Early attempts with temporary disc recording and photographic recording proved unsu...
