電磁配列を使用する記憶システム
Document Type and Number:
Japanese Patent JP2006501562
Kind Code:
A
Abstract:
A record carrier ( 40 ) of a removable type has an information plane of a layer of magnetic material on a substrate constituting an array of bit locations ( 11 ). A magnetic state of the material represents the value of each bit location. A storage device ( 35 ) has an interface surface ( 32 ) for cooperating with the information plane. The interface surface has an array ( 31 ) of electro-magnetic elements that are sensitive to said magnetic state of the electro-magnetic material. The record carrier and device have alignment elements ( 38, 41 ) for positioning the bit locations near the electro-magnetic elements within a near-field working distance between a bit location and the corresponding electro-magnetic element when the record carrier is mounted in the device.
