摘要： Although dots and servo patterns are made of the same magnetic material, the dots have a relatively low coercive force so as to allow data deletion and rewrite by a magnetic head, while the servo patterns have a high coercive force compared with the coercive force of the dots. The coercive force of the servo patterns is strong enough so as to eliminate the influence of shape magnetic anisotropy.

摘要： A magnetic recording medium is provided. The magnetic recording medium comprises an in-plane magnetic film used for recording, and a perpendicular magnetic film formed on the in-plane magnetic film. The in-plane magnetic film has a magnetization easy axis in an in-plane direction. The perpendicular magnetic film has a magnetization easy axis oriented in a direction perpendicular to the magnetization easy axis of the in-plane magnetic film. A tBr (a product of a thickness and a residual magnetization) of the perpendicular magnetic film is set so as not to exceed one-fifth of a tBr of the in-plane magnetic film at the maximum.

摘要： A storage system has a storage medium, a head, and a control unit for carrying out refresh processing. A refresh operation extracts data that needs to be refreshed by measuring the read-out output level of target data. Then, data requiring refresh is re-recorded to the storage medium by the head. Because an actual data level is observed, it is possible to accurately detect refresh target data, and because there is no need for a reference area, it is possible to prevent a reduction in storage capacity.
