Patent ID: 8369194

Claim:
An optical disc device for recording data into a recordable optical disc, the optical disc device comprising: a buffer memory configured to temporarily store the data; a recording signal processing circuit configured to generate a recording signal by: reading the data from the buffer memory, adding error correction codes to the data, encoding and modulating the data to the recording signal; and an optical pickup configured to irradiate laser light onto the recordable optical disc to record the recording signal, wherein: the recordable optical disc comprises recording regions to record the recording signal and link regions to link a recording region to the next recording region; and either a first specific pattern signal or second specific pattern signal is recorded into a link region of the recordable optical disc, the first specific pattern signal including first synchronizing signals in particular positions of the link region and specific data repeating patterns in other positions of the link region, and the second specific pattern signal including second synchronizing signals in particular positions of the link region and specific data repeating patterns, which are different from the specific data repeating patterns of the first specific pattern signal, in other positions of the link region.
