摘要：
A record carrier (40) of a removable type has an information plane that is provided with a pattern of an electro-magnetic material constituting an array of bit locations (11). The presence or absence of said material at the information plane represent the value of a bit location. The device has an interface surface (32) for cooperating with the information plane. The interface surface is provided with an array of electro-magnetic sensor elements (54,56) that are sensitive to the presence of said electro-magnetic material within a near-field working distance. The record carrier and device system have alignment means (38,41) for positioning the bit locations near the sensor elements within the near-field working distance between a bit location and the corresponding sensor when the record carrier is mounted in the device.
