摘要： PROBLEM TO BE SOLVED: To provide a suitable optical disk which can improve recording capacity by recording a control data signal in an easy-to-read format for both a read-only and rewritable type DVD disks and reducing redundant areas. SOLUTION: A recording method comprises the following steps of: dividing each truck in a read-only area into sector areas of the same capacity, for adding an error correcting code to a first data signal, constituting a second data signal, forming and recording a pit sequence in the sector, adapting the user data to be recorded to the first data in a rewritable area, adding the same error correcting code as the read only area, similarly constituting a second data signal, adding the data signal to the signal to be rewritable to constitute a third data signal, generating a format in which a header area for representing address information of the sectors is added to a recording area to record the signal, dividing the area into two areas in the radial direction to define the outer periphery area as a rewritable area and the inner periphery area as a read-only area, and recording the control data signal on the read-only area.

摘要： PROBLEM TO BE SOLVED: To provide a server device or the like for authentication capable of detecting that an identical terminal key is stored in a plurality of terminals, and of detecting which terminal key of legitimate terminals is stored in an unauthorized terminal. SOLUTION: A DVD terminal 20 makes a request for sending a sub-content to an authentication server 40 (in this case, attaches the "model name and serial number" of the DVD terminal 20) (S302). The authentication server 40 generates a random number R (S304) and sends it to the DVD terminal 20 (S306). The DVD terminal 20 reads a terminal key and a terminal ID that are stored in a terminal information memory unit 25, encrypts the received random number R using a terminal key (SK_X) (S308) and sends it and the terminal ID (ID_X) to the authentication server 40 (S310). The authentication server 40 verifies the random number R and the terminal ID that are received from the DVD terminal 20 and encrypted, and authenticates whether the DVD terminal 20 is the valid terminal or not (S312).

摘要： An optical disc using a single-spiral land and groove track format and an address signal enabling simple sector address management and format compatibility with read-only optical disc media is disclosed. Four physical address areas PID1-PID4 are recorded to a header area such that PID1 and PID2 are offset one-half track pitch toward the outside circumference of the disc from the groove track center, and PID3 and PID4 are offset one-half track pitch toward the inside circumference of the disc from the groove track center, and the header area is shared by groove track sectors and land track sectors. A groove track sector address is written to PID3 and PID4, and the sector address of the land track sector adjacent on the outside circumference side of that groove sector is written to PID1 and PID2. The address of each sector increases (1) in the same sequence as the sectors are formed in the recording spiral.

摘要： A method of recording time-division multiplexed video information about N channels of e.g., broadcasting on an optical disk wherein the data compression ratio of video information about each channel is so determined that the sum of the quantities of data on image information to be recorded in a unit time for the N channels may be almost constant irrespective of the number of channels (N), and images are recorded at the compression ratio. Another mode of recording time-division multiplexed video information about N channels of e.g., broadcasting on an optical disk is disclosed wherein the intervals between the frames to be recorded are so determined that the sum of the numbers of image frames of the N channels to be recorded in a unit time may be almost constant irrespective of the number of channels (N), the frames of each channel are thinned so as to realize the determined intervals, and video information about each channel is recorded on an optical disk.
