IPC: G11B11/14
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To enhance thermal fluctuation resistance and to enable the easy execution of writing by controlling the magnetic anisotropy of magnetic particles by using a magnetostriction effect, thereby recording information in correspondence to 1/0 or 0/1 of the data respective recording a 'detectable state' and a 'non-detectable state' of a certain magnetization component (for example, a perpendicular component). SOLUTION: The magnetic particles 12 are arranged like an array in a substrate of a material 11 which makes a volumetric change having a temp. hysteresis characteristic. The magnetization direction in the initial state of the magnetic particles 12 is an arrow 13. A stress 14 is applied on the magnetic particles 12 desired to be recorded with the information by changing the temp. of the surrounding material 11 to change the magnetization direction from the arrow 13 to an arrow 15 by the magnetostriction effect. The reading-out of the information is executed by detecting the magnetization component of the magnetic particles 12 by a head capable of reading out only the magnetization direction of either of the arrow 13 or 15.  As a result, even if the magnetization direction faces the reverse direction by the fluctuation, there is no hindrance in the detection of the magnetization component and the holding of the information is made possible.
