ABSTRACT:
There is provided an optical recording medium-manufacturing apparatus that is capable of avoiding breakage of a substrate while avoiding formation of a central hole off-center with respect to the substrate. A control section causes the vertical movement section to move an ultrasonic horn in directions toward and away from the cutting edge of a punching blade section to thereby cause the ultrasonic horn to press the disk-shaped substrate and at the same cause an ultrasonic generator to perform ultrasonic vibration at least from a time point at which the disk-shaped substrate is brought into contact with the cutting edge of the punching blade section to a time point at which the punching of the central hole is completed.
