MAGNETIC RECORDING METHOD

摘要

A magnetic recording and reproducing method by which magnetic recording and reproduction can be performed at a recording density higher than the conventional example by combining a micro-area heating means, a coil (22) for energizing magnetic field, a magneto-resistance element, and a recording film having an auxiliary recording layer (14) with each other. In this magnetic recording and reproducing method in which information recording is performed by thermomagnetic recording and information reproduction is detected from the variation of magnetic fluxes from a recording magnetic domain, the magneto-resistance element is used as the detecting means of the variation of magnetic fluxes and a solid emulsion lens, evanescent light, or a current flowing between a probe and a recording medium is used as the heating means for thermomagnetic recording. The recording medium is composed of a substrate and the recording film, and the recording film is composed of a recording layer and the auxiliary recording layer (14). The substrate can be made of silicon or silicon oxide.
