Record carrier of the optical type and a device for recording and/or playback for use with such a record carrier

A device for recording and/or playback of a record carrier of the inscribable type having a preformed track in which an auxiliary signal comprising a sequence of codes is recorded by means of a preformed track modulation, which codes comprise a sequence of address codes (AC) specifying the addresses of the track portions in which said address codes (AC) are recorded and special codes (SC) which are distinguished from said address codes (AC) and which are specifying control data for controlling a recording by a recording device and which sequence is obtained by replacing, in a sequence of address codes (AC) having consecutive address values, a plurality of said address codes by special codes (SC), wherein, the sequence comprises a periodic pattern of address codes and special codes which pattern has a predetermined positional relationship with respect to a predetermined reference address, wherein the periodic pattern is shifted by a predetermined number of frames with respect to the predetermined reference address, the device comprising:

• recording means for recording information on the record carrier in accordance with an recording process,
• reading means for reading the information recorded on the record carrier, the reading means comprising means to read the auxiliary signal recorded on a record carrier,
• selecting means for selecting and extracting the special codes and the address codes from the auxiliary signal, and
• control means for controlling the recording process, wherein, the control means are configured to determine the predetermined positional relationship of the periodic pattern of address codes and special codes and to control the recording process in accordance with said determination.

An optically inscribable record carrier disc, having

• a preformed track defining an auxiliary signal comprising
• a sequence of codes formed by a preformed track modulation, which codes comprise
• a sequence of address codes (AC) specifying the addresses of the track portions in which said address codes (AC) are recorded and
• special codes (SC) which are distinguished from said address codes (AC) and which are specifying control data for controlling a recording by a recording device, and
• which sequence is obtained by replacing a sequence of address codes (AC) having consecutive address values with special codes (SC),
• wherein said sequence comprises a periodic pattern of address codes and special codes which pattern has a predetermined positional relationship with respect to an additional piece of information, and
• wherein the periodic pattern is shifted by a predetermined number of frames with respect to the predetermined reference address.

A device for recording and/or playback of an optically inscribable record carrier disc, the record carrier disc having a preformed track defining an auxiliary signal comprising a sequence of codes indicated by a preformed track modulation, which codes comprise a sequence of address codes (AC) indicating the addresses of the track portions in which said address codes (AC) are recorded and special codes (SC) which are distinguished from said address codes (AC) and which indicate control data for controlling the recording by the recording and/or playback device, and which sequence is obtained by replacing a sequence of address codes (AC) having consecutive address values with special codes (SC), wherein said sequence comprises a periodic pattern of address codes and special codes which pattern has a predetermined positional relationship with respect to an additional piece of information, wherein the periodic pattern is shifted by a predetermined number of frames with respect to the predetermined reference address, the device comprising:

• recording means for recording information on the record carrier in accordance with a recording process and in accordance with the control data,
• reading means for reading the information recorded on the record carrier, the reading means comprising means to read the auxiliary signal recorded on a record carrier,
• selecting means for selecting and extracting the special codes and the address codes from the auxiliary signal, and
• control means for controlling the recording process, wherein the control means are configured to detect the predetermined positional relationship of the periodic pattern of address codes and special codes and to control the recording process in accordance with said detection.
