Patent ID: 7057834

Claim:
A method for producing an in-plane magnetic recording medium, the method comprising the step of: bringing a surface of a master information carrier in close contact with a surface of the in-plane magnetic recording medium, the surface of the master information carrier having an information signal according to a figuration pattern of an array of ferromagnetic thin films that are deposited on a surface of a substrate, and applying a magnetic field thereto, so as to record the information signal corresponding to the array of the ferromagnetic thin films as magnetization information in the in-plane magnetic recording medium, wherein a length of each ferromagnetic thin film on the master information carrier, corresponding to a distance between a pair of magnetic transition areas adjacent to each other in the magnetization information recorded in the in-plane magnetic recording medium, is set to be larger than a distance between the magnetic transition areas that is desirable for a signal recorded in the in-plane magnetic recording medium.
