OBJECTS TO PROVIDE A MAGNETIC RECORDING MEDIUM AND THE MANUFACTURING METHOD THEREOF WHICH FACILITATE PREVENTING THE LUBRICANT DEPOSITED ON THE END FACE OF THE MAGNETIC RECORDING MEDIUM FROM MIGRATING ONTO THE MAJOR SURFACES THEREOF.MEANS FOR ACHIEVING THE OBJECTS THE LUBRICANT DEPOSITED ON THE END FACE OF A MAGNETIC DISK (11), WHICH MAY MIGRATE ONTO THE MAJOR SURFACES OF MAGNETIC DISK (11), IS WIPED OFF BY ROTATING MAGNETIC DISK (11) WITH THE LIBRICANT DEPOSITED THEREON, BY SPRAYING A SOLVENT ONTO A WIPING TAPE (13) WHILE FEEDING WIPING TAPE (13), AND BY PRESSING WET WIPING TAPE (13) CONTAINING THE SOLVENT TO THE END FACE OF MAGNETIC DISK (11) WITH A PAD (14) WHILE THE FEED OF WIPING TAPE (13) IS STOPPED, OR THE LUBRICANT DEPOSITED ON THE END FACE OF A MAGNETIC DISK (11) IS SOLIDIFIED TO DEPRIVE THE LUBRICANT OF THE FLUIDITY THEREOF BY ROTATING MAGNETIC DISK (11) WITH THE LUBRICANT DEPOSITED THEREON AND BY IRRADIATING AN ULTRAVIOLET RAY FROM AN UV LAMP (18) THROUGH A SLIT (20) OPENED IN A SHIELD (19) TO THE END FACE OF MAGNETIC DISK (11).
