Optical rotating recording apparatus and method with address information and corresponding error correction code

A method of recording address information for writing only one address corresponding to an address information recording region of at least one of a land and a groove of an optical rotating recording medium, including the steps of:

• generating an error correction code for a corresponding address;
• and
• recording the only one address and said generated error correction code in said address information recording region,
• wherein the optical rotating recording medium includes only one error code corresponding to the address, the only one error code being the generated corresponding error correction code.

A method of recovering address information, including the steps of:

• reading one address and a corresponding error correction code recorded in an address information recording region of an optical rotating recording medium recorded with said one address and the error correction code generated for the address information in the address information recording region in a header of at least one of a land and a groove;
• correcting the read address by the error correction code when there is an error in the one read address;
• and
• treating the correctly corrected address as a normal address and, when not correctly corrected, estimating and outputting a present address from at least one previous correct address in view of continuity of addresses.

An optical recording apparatus, comprising:

• an address information generation means for generating an error correction code for each address of at least one of a land and a groove of an optical rotating recording medium and combining one of the addresses and a generated error correction code;
• and
• a recording means for recording a combined address and error correction code in an address information recording region of said at least one of the land and the groove on said optical rotating recording medium,
• wherein a header including said address information recording region includes only one address and a corresponding error correction code generated for said only one address, and
• wherein the optical rotating recording medium includes only one error code corresponding to the address, the only one error code being the generated corresponding error correction code.

An optical recording/reproducing apparatus, comprising:

• an address information generation means for generating an error correction code for each address of at least one of a land and a groove on an optical rotating recording medium;
• a recording means for recording only one address and a generated error correction code in an address information recording region of said at least one of the land and the groove on said optical rotating recording medium;
• an optical detection means for reading said only one address and said corresponding error correction code recorded in the address information recording region of said optical rotating recording medium recorded with said only one address and the error correction code generated for the address information in the address information recording region in a header of the at least one of the land and the groove;
• and
• an address information recovery means for correcting any error in the said only one address detected by said optical detection means by said detected error correction code and using the correctly corrected address as a normal address and for estimating and outputting a present address from at least one previous correct address from the continuity of addresses when not correctly corrected.

An optical recording medium, comprising:

• a land or a groove area located on the recording medium;
• and
• a header region recorded in the land or the groove area, said header including address information recording region,
• wherein a single address and a corresponding error correction code generated for the single address are recorded in the address information recording region, and
• wherein the optical rotating recording medium includes only one error code corresponding to the address, the only one error code being the generated corresponding error correction code.

A method of recording address information in an optical recording medium, comprising:

• generating an error correction code for a single address written in an address information recording region of a land and/or groove of the optical recording medium;
• and
• recording the single address and the generated error correction code in said address information recording region,
• wherein the optical rotating recording medium includes only one error code corresponding to the address, the only one error code being the generated corresponding error correction code.

A method of recording information in an optical recording medium, comprising:

• generating an error correction code for an address written in an address information recording region of a land and/or groove of the optical recording medium;
• combining the address and the generated error correction code;
• and
• recording the combined address and the generated error correction code in said address information recording region,
• wherein the optical rotating recording medium includes only one error code corresponding to the address, the only one error code being the generated corresponding error correction code.
