Direct measurement of the field from a magnetic recording head using an InAs Hall sensor on a contact write/read tester

At 1Tbit/in2 areal density magnetic recording dimensions, reliable magnetic field metrology does not exist. One technique to map the spatial profile of the magnetic field of a write head is to use a contact read/write tester. A magnetic recording head is brought into contact with a Hall sensor, and...
