Abstract

PURPOSE: To eliminate protrusions on the medium surface efficiently by bringing mimic heads into contact with the disc medium surface continuously to perform the varnish process in production of a magnetic disc medium.
CONSTITUTION: In the varnish process for magnetic disc medium 1 where the polish process for the magnetic applied film formed on the disc substrate is completed, mimic head 2 which scans the surface of medium 1 through arm 3 to eliminate protrusions on the surface is not floated for rotating magnetic disc medium 1 but is brought into contact with disc medium 1, and under this state, medium 1 is rotated. For the purpose of bringing mimic head 2 into contact with disc medium 1, a non- floating structure is given to the slider part of mimic head 2, or rotation of disc medium 1 is made slow to perform the varnish process.
