PURPOSE:To obtain a sufficient polishing effect even if the traveling speed of the magnetic recording medium having a relatively thin film thickness is high by polishing the magnetic recording medium while nearly uniformly pressing the entire part of the contact part of a polishing member and the magnetic recording medium by compressed air. CONSTITUTION:The magnetic recording medium 4 is polished while the entire part of the contact part of the polishing member 3 and the magnetic recording medium 4 is uniformly pressed by the compressed air at the time of polishing the magnetic recording medium 4 while bringing the magnetic recording medium 4 into contact with the polishing member consisting of a base and abrasive grain layer during traveling. The entire part of the contact part of the magnetic recording medium 4 and the polishing member 3 is pressed by the compressed air nearly under the specified pressure even if the magnetic recording medium 4 is made to travel at the high speed in contact with the polishing member 3 in order to polish the coated film. The intrusion of the air is prevented in this way and the sufficient contact between the magnetic recording medium and the polishing member is obtd. Further, the generation of the oscillation of the recording medium is prevented and, therefore, the generation of wrinkles is obviated and the good polishing characteristic is obtd. |
