Erasable magneto-optical recording media

Magnetization reversal mechanisms and time-dependent processes in thin Tb/Fe multilayer films

“…E-mail address: tt@stand.ac.uk have been proposed. These schemes can be grouped into four categories: magnetic field modulation [5], optical modulation using single-layer direct overwrite materials [6], erase before write techniques [7] and optical modulation using multiple-layer exchange coupled materials [8].…”

Les amorphes métalliques et leurs propriétés magnétiques

“…alliages à magnétostriction nulle pour les applications en régimes hautes fréquences [25,27], -alliages en films minces pour les dispositifs d'enregistrement et les supports de mémoires [26,[28][29][30][31][32], -alliages en films minces à magnétostriction élevée pour les applications en ondes acoustiques de surfaces, palpeurs, jauges de contrainte, etc. [30, 31, 33, 34], -les applications générales des amorphes magnétiques doux obtenus sous diverses formes par trempe du liquide [2, 23,25,[35][36][37][38][39][40][41][42][43][44],…”

The CD-ROM Drive

“…Designated as P and Q, each of these sequences forms a Reed-Solomon codeword together with the two corresponding parity bytes. The error detection and correction uses (26,24) and (45,43) RS codes for th~ P and Q sequences, respectively (see also Section 4.7). As the minimum distance dm = 3 for both sequences, it will be possible to either detect exactly the location of 2 erroneous bytes within a codeword or directly correct one byte in error.…”
