Claim:
A method for recording control information on a recording medium, comprising: generating control information for controlling recording/reproducing data on/from the recording medium, the control information including a first speed information used to indicate a maximum recording speed, a second speed information used to indicate a minimum recording speed, and a third speed information used to indicate one or more basic recording speeds, wherein the third speed information represents whether each of the basic recording speeds are applicable to the recording medium or not, and at least one of the basic recording speeds has to be supported by the recording medium; and recording the control information on a specific area of the recording medium, wherein the control information further comprises an applicable recording speed information indicating an applicability of a specific recording speed, wherein the applicable recording speed information represents the specific recording speed in a bit position, and wherein the applicable recording speed information is configured in a manner that a bit position for a higher recording speed is set to indicate that the higher recording speed is applicable or inapplicable if a bit for a lower recording speed is set to indicate 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.
