Patent ID: 7257060

Claim:
A data recording method of recording encoded content data in encode units onto a recording medium which is divided into sectors of a predetermined length, each sector including a user data area of fixed length, and can be accessed on said sector unit basis, comprising: dividing encoded content data every predetermined length, adding a header and packetizing into packets, each packet including a data area, wherein a size of the encode units is determined independent of a size of the packets; further adding a pack header of fixed length, a PES header of fixed length, and a stream header of fixed length to each packet to thereby form pack data, wherein each pack data has a same fixed length as the user data of each sector, wherein the pack header includes data as to a stuffing length of stuffing data inserted into the data area, and the PES header includes scrambling control data controlling scrambling of data in the data area; recording said data which has been packetized and further formed as pack data into each of the sectors on said recording medium in correspondence to said sectors; and when said encoded content data is divided every predetermined length and packetized, recording into the stream header an encode unit pointer indicative of a start position of a complete encode unit among a plurality of encode units which are arranged in one of said packets within one sector into the header of said one packet.
