Abstract:
1. A recordable data storage medium, including a burst cutting area on which property data, unique to the recordable data storage medium, was recorded and, an information area on which user data to be used by a user is written, wherein the user data is written on the information area in the same format as a first data format for a read-only data storage medium, on which user data to be used by the user was written in the first data format and on which property data, unique to the read-only data storage medium, was recorded in a second data format, wherein at least a portion of the property data was recorded on the burst cutting area of the recordable data storage medium in a third data format that is different from the second data format, and the third data format uses a different modulation method from that of the second data format and satisfies an inverted polarity relationship with respect to the modulation method of the second data format, and the modulation method for the second data format is a method of converting data “0” into channel data “10” and data “1” into channel data “01”, respectively, and the modulation method for the third data format is a method of converting data “0” into channel data “01” and data “1” into channel data “10”, respectively, and there are plurality of barcode-like marks in the burst cutting area, extending in the radial direction and arranged in a circumferential direction.
