Abstract
A method of producing magnetic recording disks includes positioning the disks between flat plates and increasing the temperature and pressure on the disks. Servo tracks are embossed on the disks by an embossing pattern on the flat plate. Servo tracks may be applied by a printing pattern on the flat plates. The flat plates are rotated during the process to relieve directional differences in the modulus of elasticity of the disk.
