Beschreibung
Zusammenfassung:	A metal plate having a pattern of protrusions on a first surface thereof is produced; photoresist is provided on a second surface of the metal plate; the photoresist is removed from a portion of the metal plate corresponding to a loop shaped outer peripheral cutout region that contacts the outer periphery of a mold region of the metal plate; and the metal plate is etched using the remaining photoresist as a mask, in a method for producing and a method for cutting a processing a master mold having a pattern of protrusions and recesses corresponding to data to be transferred on a surface thereof.
