Integrated servo and read EMR sensor
摘要:
An integrated servo and read device implementing Extraordinary Magnetoresistive (EMR) sensors. In one embodiment, dedicated EMR sensors are employed: one for data reading and one for servo operations. The sensors are preferably configured in an abutted configuration. In addition to magnetic recording systems, the device is also useful in a magnetic imaging device such as a scanning magnetometer. The integrated device may also be useful in other devices requiring a high sensitivity, high resolution sensor.
