A relatively new optical storage technology which combines laser and magnetic methods to read and write from a platter. Information stored by local magnetization of a magnetic medium, using a focused light beam to produce local heating and consequent reduction of coercivity so that a moderately strong, poorly localized magnetic field can flip the state of a small region of high coercivity material. Reading is done either magnetically, with inductive heads in close proximity to the medium, or optically, through rotation of the plane of polarization of probing light via the Faraday effect or Kerr effect. 4, record 1, English, - magneto%2Doptical%20storage

Méthode de stockage employée dans les unités de disques optiques pouvant être réécrits; elle combine les techniques d’enregistrement magnétiques et optiques. Le disque est recouvert d’un film qui est uniformément magnétisé au départ. Un rayon laser est utilisé pour démagnétiser une petite zone sur le film en la portant à une température supérieure à la température critique(le point de Curie ou point de compensation), et l'application d’un champ magnétique local détermine ensuite la direction dans laquelle cette zone sera magnétisée lorsqu'elle refroidira. Pour lire l'information, le disque est balayé par un rayon de lumière polarisée émis par un laser de faible puissance. Le plan de polarisation d’une lumière qui est réfléchie par une surface magnétisée tourne en fonction de la direction du champ magnétique-c'est l'effet de Kerr. 2, record 1, French, - m%C3%A9moire%20magn%C3%A9to%2Doptique

A process for reducing a magnetized material to a neutral state, that is, to a state when both the magnetic induction B and the magnetic field strength H are equal to zero. (...) The standard demagnetization process involves applying a magnetizing force above a critical value for the material used, and successively reversing H in direction as the value of H is steadily reduced to a value less than those to be used in subsequent experiments. If the final value of H is essentially zero, the specimen is demagnetized. 4, record 2, English, - demagnetization

Démagnétisation des têtes : Tout enregistrement provoque une certaine magnétisation permanente des guides de métal et des têtes qui, à la longue, si elles ne sont pas démagnétisées, peuvent endommager le ruban, en plus d’augmenter le chuintement. Pour ce faire, vous utilisez un électro-aimant spécial que vous passez lentement le long des pièces métalliques(guides, têtes, arbre) [...]. Coupez l'alimentation du secteur. Approchez le démagnétiseur lentement des parties à démagnétiser, laissez un temps en passant de bas en haut, puis retirer très, très lentement pour éviter une nouvelle magnétisation. 3, record 2, French, - d%C3%A9magn%C3%A9tisation
