Patent ID: 7460453

Claim:
A method for recording/reproducing data on/from a recording medium, comprising: reading recording speed information from a specific area of the recording medium, the recording speed information including a first information used to indicate a first recording speed as a maximum recording speed, a second information used to indicate a second recording speed as a minimum recording speed, a third information used to indicate a third recording speed as a predetermined recording speed different from the maximum and minimum recording speeds, and a fourth information used to indicate a fourth recording speed as a basic recording speed, wherein at least one basic recording speed has to be supported by the recording medium; recording/reproducing the data on/from the recording medium according to the read recording speed information; reading write strategy parameters associated with a specific recording speed, the write strategy parameters including write power and pulse timing for recording the data on the recording medium; and reading recordable speed information indicating whether a specific recording speed is applicable to the recording medium, wherein the fourth information is used to indicate one or more basic recording speeds and represents whether said one or more basic recording speeds are applicable to the recording medium, wherein the recordable speed information indicates the specific recording speed in a bit position, and wherein the recordable speed information is configured in a manner that a bit position for a higher recording speed indicates that the higher recording speed is applicable or inapplicable if a bit position for a lower recording speed indicates that the lower recording speed is applicable, and the bit for the higher recording speed indicates only that the higher recording speed is inapplicable if the bit for the lower recording speed indicates that the lower recording speed is inapplicable.
