ABSTRACT Electrical Engineering/History of Technology Magnetic Recording The First 100 Years The first magnetic recording device was demonstrated and patented by the Danish inventor Valdemar Poulsen in 1898. Poulsen made a magnetic recording of his voice on a length of piano wire. Magnetic Recording traces the development of the watershed products and the technical breakthroughs in magnetic recording that took place during the century from Poulsen’s experiment to today’s ubiquitous audio, video, and data recording technologies, including tape recorders, video cassette recorders, and computer hard drives. An international author team brings a unique perspective, drawn from professional experience, to the history of magnetic recording applications. Their key insights shed light on how magnetic recording triumphed over all competing technologies and revolutionized the music, radio, television, and computer industries. They also show how these developments offer opportunities for future applications. Magnetic Recording features 116 illustrations, including 92 photographs of historic magnetic recording machines and their inventors.

    ABSTRACT: In this article, we examine the role that oral corpora – i.e. well-structured systematic recordings of spoken language – can play in French language education within the francophonie (the French-speaking world). We first provide a brief overview of the relatively thin relationship between French language education and oral corpora since the end of the 19th century, followed by an introduction to one of the most recent and renowned corpora in the field of French language studies, the PFC corpus (Phonologie du Français Contemporain – Phonology of Contemporary French), which was started ten years ago by a large international research group (Durand, Laks & Lyche 2002). The pedagogical exploitation of the PFC database - both online and offline - is the general objective of the ongoing PFC-EF programme (Enseignement du français – teaching of French), which was launched three years ago (Detey & Nouveau 2006) and which we describe in the second part of the article. Two aspects of the programme are underlined: its focus on orality and its capacity to handle linguistic variation, particularly – but not solely - from a geolinguistic viewpoint. Finally, we place the emphasis on methodological perspectives and put forward a few recommandations for turning linguistic data into pedagogical resources (Detey, Durand, Laks & Lyche to appear).

    ABSTRACT: Controlled self-assembly of magnetic L1 0 FePt and CoPt nanoparticles has stimulated great interest recently and may serve as future ultrahigh-density data storage media. This article reviews chemical synthesis of self-assembled FePtCu nanoparticles film and fabrication of CoPt/C and FePt/C granular thin films by sputtering. Their novel structural characterization and unique magnetic properties are also reviewed. Firstly, monodispersed nanoparticle arrays of FePtCu with varying composition were synthesized by chemical reduction of Pt and Cu reagents and thermal decomposition of Fe pentacarbonyl in the presence of oleic acid and oleyl amine stabilizers. As prepared particles had FCC structure with an average diameter of 3.5 nm and were superparamagnetic. The particles were well dispersed in hydrocarbon solvents and could be self-assembled into two or three dimensions particles arrays with a variety of close-packing arrangements. Heat-treatment of the self-assembled films at temperatures above 550°C transformed the particles from the FCC to the L1 0 phase, giving in-plane coercivities as high as 9 kOe. X-ray diffraction revealed that the Cu remained in the annealed FePtCu films. The magnetic hysteresis curves could be decomposed into a hard component (H c > 5 kOe) and a soft component (H c < 2 kOe). On the other hand, CoPt and FePt nanoparticles embedded in non-magnetic C matrix have been obtained by annealing CoPt/C and FePt/C multilayer precursors deposited onto Si substrate at different substrate temperature. The magnetic and structural properties of the films were investigated with respect to bilayer thickness, annealing conditions and temperature. Ordered FePt nanoparticles with average particle size from a few nanometers to about 20 nm were obtained directly by depositing at high substrate temperature. These particles showed higher magnetic ordering than particles made via multilayer precursors. With a certain FePt to C ratio, films showed strong perpendicular anisotropy.
