Patent ID: 8036071

Claim:
A method of producing an information recording medium having a recording format, such that (i) information can be recorded to a recording track of a recording layer according to only one of a groove recording system and a land recording system, and (ii) the recording track to which the information can be recorded has a wobbled track including a wobble and address information added to the wobble by performing MSK (Minimum Shift Keying) modulation and HMW (Harmonic Modulated Wave) modulation to a reference frequency signal of the wobble, the method of producing the information recording medium comprising: a step of forming the recording layer of the information recording medium, such that the formed recording layer includes a land track and a groove track that is closer to an incident laser beam than the land track, wherein the recording track of the formed recording layer is only one of the land track and the groove track, the step of forming the recording layer comprising: selecting one of the land recording system, which allows information to be recorded only on the land track as the recording track, and the groove recording system, which allows information to be recorded only on the groove track as the recording track; setting a first wobble deviation of the wobble on the recording track at a beginning point of the wobbled track, such that a physical direction toward which the first wobble deviation starts from the beginning point of the wobbled track only when the land recording system is selected is a mirror reverse of a physical direction toward which the first wobble deviation starts from the beginning point of the wobbled track only when the groove recording system is selected; and forming the wobble, to which the address information is added, on the wobbled track on the recording track of the recording layer according to (i) only the selected one of the land recording system and the groove recording system, and (ii) the first wobble deviation of the wobble set by the setting of the first wobble deviation of the wobble.
