RECORD MEDIUM WITH DIFFERENT LATENCIES |
摘要 |
Latency information is used for coding of additional information in a record medium. This additional information which gets embossed in the record medium might be used for verification purposes in that only storage media with the correct latency information are judged to be authentic or might be decoded in a proper way. This technique is applicable to record media, recordable record media, an emulator for recordable or non-recordable record media, a method for producing recordable or non-recordable record media, a method for verifying recordable or non-recordable record media, a record medium writing device for producing recordable or non-recordable record media, and a record medium accessing device for verifying recordable or non-recordable record media. |
