    摘要： Disclosed is a magnetic recording medium comprising a substrate, a magnetic recording layer formed on the substrate to record magnetic information, and a piezoelectric material disposed adjacent to the magnetic recording layer and capable of contracting and expanding. Preferably, piezoelectric members made of the piezoelectric material are formed in such a manner as to be spaced a predetermined distance apart from each other on the substrate in a direction crossing a track on the magnetic recording layer, and the magnetic recording layer is formed between the piezoelectric members. When subjected to laser light or ultraviolet radiation, the piezoelectric material contracts or expands at least in the direction crossing the track. The piezoelectric material is selected from the group consisting of lead lanthanum zirconate titanate, barium titanate, and potassium niobate.

    摘要： A magnetic recording medium has a substrate, a first granular layer formed on the substrate, the first granular layer having a plurality of a first magnetic grains and a first oxide for separating the plurality of first magnetic grains from one another. A non-magnetic layer is formed on the first granular layer. The second granular layer is formed on the non-magnetic layer which has a plurality of second magnetic grains and a second oxide for separating the plurality of second magnetic grains from one another. The anisotropic magnetic field of the first granular layer is more intensive than that of the second granular layer.
