摘要：
In recording information, an SMPTE 339M-defined UMID buried in video and audio material signals to be recorded to a magnetic tape (30) or a UMID generated from information other than the material signals, is written to a contactless memory tag (37), whereby it is made possible to acquire a UMID for material signals recorded in the recording medium without having to actually read the material signals recorded in the recording medium and use the UMID for data search, validation, etc.
