IPC: G11B5/80
Filed: 1993-05-12
Abstract: PURPOSE:To provide a magnetic recording medium and its production method so that identification information such as magnetic bar codes or the like can be accurately judged in a information processing device for magnetic information at high reading speed. CONSTITUTION:A magnetic layer 1 containing a photosetting type resin is formed on a nonmagnetic substrate S-1. Most of the magnetic material which constitutes the magnetic layer 1 is magnetically oriented in a specified direction to the coating direction of the layer 1. A part of the magnetic material has no orientation or is oriented in another direction different from the orienting direction above described. The magnetic layer 1 is formed by applying a magnetic coating material containing a photosetting resin on the nonmagnetic substrate 1. This magnetic layer 1 is irradiated with light energy for patterning so that the layer is partly hardened in the irradiated area. Further, the magnetic layer 1 remaining not hardened is magnetically oriented in a specified direction to the coating direction (15), and then the whole magnetic layer is hardened with light energy (17).
