An information storage medium comprising:

• a user data area;
• and
• a read-only area,
• wherein formal recording speed information, which is reproduced by a differential signal channel, is recorded on the read-only area, and recordable speed information, which is reproduced by a sum channel, is recorded in a recordable zone of an area other than the user data area, and
• wherein the formal recording speed information indicates a recording speed suggested by a manufacturer for recording data on the information storage medium, and the recordable speed information indicates an effective recording speed obtained, via actual testing of predetermined recording characteristics of the information storage medium.

An information storage medium comprising:

• a user data area;
• and
• a read-only area,
• wherein formal recording speed information, which is in a pit shape that is reproduced using a sum channel, is recorded on the read-only area, and recordable speed information, which is reproduced by the sum channel, is recorded in a recordable area other than the user data area, and
• wherein the formal recording speed information indicates a recording speed suggested by a manufacturer for recording data on the information storage medium, and the recordable speed information indicates an effective recording speed obtained, via actual testing of predetermined recording characteristics of the information storage medium.

A method of recording and/or reproducing data on/from an information storage medium having a lead-in area, a user data area, and a lead-out area, the method comprising:

• recording formal recording speed information in a read-only data zone of at least one of the lead-in area and the lead-out area;
• and

• wherein the formal recording speed information indicates a recording speed suggested by a manufacturer for recording data on the information storage medium, and the maximum recordable speed information indicates an effective maximum recording speed obtained, via actual testing of predetermined recording characteristics of the information storage medium.

A method of recording and/or reproducing data on/from an information storage medium having a lead-in area, a user data area, and a lead-out area, the method comprising:

• recording formal recording speed information in a read-only data zone of at least one of the lead-in area and the lead-out area;
• and
• recording recordable speed information in a re-recordable data zone of at least one of the lead-in area and the lead-out area,
• wherein the formal recording speed information indicates a recording speed suggested by a manufacturer for recording data on the information storage medium, and the recordable speed information indicates an effective recording speed obtained, via actual testing of predetermined recording characteristics of the information storage medium.

A method of recording and/or reproducing data with respect to an information storage medium having a lead-in area, a user data area, and a lead-out area, the method comprising:

• obtaining designed recording information from a read-only data zone of at least one of the lead-in and lead-out areas;
• obtaining recordable speed information from a re-recordable data zone of at least one of the lead-in and lead-out areas;
• and
• recording data at a recordable speed of the recordable speed information in accordance with the formal recording information,
• wherein the designed recording information indicates a recording speed designed by a manufacturer for recording data on the information storage medium, and the recordable speed information indicates an effective recording speed obtained, via actual testing of predetermined recording characteristics of the information storage medium.

An information storage medium comprising:

• a user data area;
• and
• a read-only area,
• wherein designed recording speed information of the information storage medium is recorded on the read-only area and recordable speed information of the information storage medium is recorded in a readable zone of an area other than the user data area, and
• wherein the designed recording speed information indicates a recording speed designed by a manufacturer for recording data on the information storage medium, and the recordable speed information indicates an effective recording speed obtained, via actual testing of predetermined recording characteristics of the information storage medium.

An information storage medium comprising:

• one or more recording layers;
• a user data area;
• and
• a read-only area,
• wherein designed recording speed information and recordable speed information on one or more recording layers of the information storage medium are recorded so as to have the same reproduction channel characteristics or different reproduction channel characteristics, and
• wherein the designed recording speed information indicates a recording speed designed by a manufacturer for recording data on the information storage medium, and the recordable speed information indicates an effective recording speed obtained, via actual testing of predetermined recording characteristics of the information storage medium.
