Hexagonal Ba-ferrite films were prepared by a facing targets sputtering system at room temperature, 100 and 500 degrees C and successively annealed in the air to crystallize. The films prepared at low temperature exhibit coercivities ranging from 1.0 to 3.8 kOe upon elevating the annealing temperature from 650 to 900 degrees C. The read/write performance of Ba-ferrite rigid disk was evaluated by using a MIG type head and the recording density D-50 was 90kfrpi.
