Information-processing apparatus, information-recording apparatus, information-processing system, information- recording method, program for information recording, and storage medium

A system for processing information, comprising:

• an apparatus for processing information which requests for recording of user data into an information-recording apparatus for recording in an information-recording medium having a plurality of recording layers, each of the layers having a data area for recording the user data, and having a first recording layer to be a reference for determining a position of said data area in each of recording layers, and a second recording layer excluding the first recording layer, the apparatus for processing information including,
• designating means for modifying the data area configured to make a designation to said information-recording apparatus regarding the size of the data area for said first recording layer within an extent of an initial-data area preset for said information-recording medium such that the data area to be used for the recording of the user data is allocated to said first recording layer and to said second recording layer;
• and
• an apparatus for recording information which makes a recording based on a request from the information-processing apparatus for recording of user data in the information-recording medium having the plural recording layers, each of the layers having a data area for recording the user data, and having the first recording layer to be a reference for determining the position of said data area in said each of the recording layers, and the second recording layer excluding the first recording layer, the apparatus for recording information including,
• means for modifying the data area configured to make a setting regarding the size of the data area for said first recording layer within the extent of the initial-data area preset for said information-recording medium upon receiving a designation of modifying the data area from said information-processing apparatus.

A method of recording information for recording in an information-recording medium having a plurality of recording layers, each of the layers having a data area for recording user data, comprising:

• modifying a data area on a first recording layer within an extent of an initial-data area preset for said information-recording medium;
• setting a first address of a data area on a second recording layer being the inverse of a last address of said data area on said first recording layer;
• and
• shifting a start address of a middle area on said first recording layer following the last address of said data area on said first recording layer, a last address of a middle area on said second recording layer being the inverse of said start address of said middle area on said first recording layer;
• wherein said information-recording medium is an information-recording medium to be recorded according to an Opposite Track Path (OTP) technique.

A method of recording information for recording in an information-recording medium having a plurality of recording layers, each of the layers having a data area for recording user data, comprising:

• modifying a data area on a first recording layer within an extent of an initial-data area preset for said information-recording medium;
• setting a first position of a data area on a second recording layer being the same radial position as a last position of said data area on said first recording layer;
• and
• shifting a start position of a middle area on said first recording layer following said last position of said data area on said first recording layer, a last position of a middle area on said second recording layer being the same radial position as said start position of said middle area on said first recording layer;
• wherein said information-recording medium is an information-recording medium to be recorded according to an Opposite Track Path (OTP) technique.

A computer-usable medium having a program for recording information being installed in a computer provided in an information-recording apparatus for making a recording based on a request from an information-processing apparatus for recording of user data in an information-recording medium having a plurality of recording layers, each of the layers having a data area for recording user data, and having a first recording layer to be a reference for determining a position of said data area in said each of the layers, and a second recording layer excluding the first recording layer, and causing said computer to:

• modify a data area on said first recording layer within an extent of an initial-data area preset for said information-recording medium;
• set a first address of a data area on said second recording layer being the inverse of a last address of said data area on said first recording layer;
• and
• shift a start address of a middle area on said first recording layer following the last address of said data area on said first recording layer, a last address of a middle area on said second recording layer being the inverse of said start address of said middle area on said first recording layer;
• wherein said information-recording medium is an information-recording medium to be recorded to an Opposite Track Path (OTP) technique.
