Optical information recording medium, information recording method for optical information recording medium and optical information recording device

A method of recording predetermined information in a user data area with laser light on an optical information recording medium including the user data area in which user data can be recorded and a management area which has information required to control recording conditions when data is recorded in the user data area, comprising:

• reading information in a recording format management area that is provided in the management area and determining the format of the data when the data is recorded in the user data area;
• reading and collating information in a recording condition management information area and/or information in an authentication identification area;
• and
• converting the user data into a predetermined signal form according to the collation result and recording the user data in the user data area of the optical information recording medium,
• wherein the information in the recording format management area, the information in the recording condition management information area, and the information in the authentication identification area are recorded in forms selected from the group consisting of pit arrangement, a wobble provided in a guide grove, a land pre-pit, and a bar code, and at least one of the form of the information in the recording format management area, the form of the information in the recording condition management information area, or the form of the information in the authentication identification area is different from the other form(s) so that even when all of the data written in the recording area is copied to a different optical information medium, the data can be inhibited from being read from the different optical information recording medium.

An optical information recording device for recording predetermined information in a user data area with laser light in an optical information recording medium including the user data area in which user data can be recorded and a management area which has information required to control recording conditions when data is recorded in the user data area,

• wherein the optical information recording device reads information in a format management area that is provided in the management area and determines the format of the data when the data is recorded in the user data area,
• the optical information recording device reads and collates information in a recording condition management information area and/or information in an authentication identification area, and
• the optical information recording device converts the user data into a predetermined signal form according to the collation result and records the user data in the user data area of the optical information recording medium,
• wherein the information in the recording format management area, the information in the recording condition management information area, and the information in the authentication identification area are recorded in forms selected from the group consisting of pit arrangement, a wobble provided in a guide grove, a land pre-pit, and a bar code, and at least one of the form of the information in the recording format management area, the form of the information in the recording condition management information area, or the form of the information in the authentication identification area is different from the other form(s) so that even when all of the data written in the recording area is copied to a different optical information medium, the data can be inhibited from being read from the different optical information recording medium.
