Abstract

PURPOSE:To increase a recording speed up to about mus by increasing recording density by forming distortion in the same pattern on adjacent magnetic recording layers, and then performing magnetic recording by a magnetostrictive contrary effect. CONSTITUTION:Over a piezoelectric crystal thin plate 2, an electric conductor having a 1 mum diameter is arranged at an about 0.5mum interval, thus obtaining a counter electrode 4. In the piezoelectric crystal 2, a pattern of distortion is formed and on a magnetic recording layer 1, destortion having substantially the same pattern with it is formed to perform magnetic recording by a magnetostrictive contrary effect. The piezoelectric crystal thin plate 2 is brought into close contact with the magnetic recording layer 1, and a photoelectric conductive film 5 is adhered onto it; and a light-transmissive electrode 6 is provided, and a normal electrode 3 is provided on the opposite side. When the electrode 6 is irradiated with luminous flux, the film 5 conducts corresponding to the exposure pattern to form the pattern of distortion on the piezoelectric crystal 2. The light-transmissive electrode 6 may use In2O3.
