Abstract:
1. A method of recording and/or reproducing data in an information storage medium, the method comprising: recording, as reproduction-only data in a reproduction-only area, maximum recording speed information, minimum recording speed information, maximum reproducing speed information, and minimum reproducing speed information, which are used to indicate speed capabilities to a drive; and recording on the information storage medium when a recording speed capability of the drive is equal to or between the minimum speed recording information and the maximum recording speed information or reproducing data from the information storage medium when a reproducing speed capability of the drive is equal to or between the maximum reproducing speed information and the minimum reproducing speed information, wherein the maximum recording speed information, the minimum recording speed information, the maximum reproducing speed information, and the minimum reproducing speed information include maximum multiple speed data and minimum multiple speed data, the minimum multiple speed data being recorded in the first four bits of the 8 bits of an m-th byte of the reproduction-only area, and the maximum multiple speed data being recorded in the last four bits of the 8 bits of the m-th byte of the reproduction-only area.
