Com-Ser

COM-SER Kft. (translates to Com-Ser Ltd.) was established in January, 1989. In the 2000s-2010s, its main profile was optical disc manufacturing (CD-ROM, Audio CD, DVD, Blu-ray, 3D Blu-ray). In fact they acted as brokers, outsourcing the actual manufacturing, most commonly to TAKT. As of September, 2020 they do not appear in the official Hungarian company database as under liquidation, but based on their non-functioning website they seem to be inactive. LCCN how-to: Discs that were identified to be brokered by Com-Ser have a matrix string as the following: DVDs: 21xxxxxxxxxxx L-[M] COMSER-DVD-[N] CDs: 21xxxxxxxxxxx COMSER-CD-[N] where 21xxxxxxxxxxx is a 13-digit matrix number assigned by TAKT, [N] - number of layer. Either 0 or 1. [M] - job number assigned by Com-Ser. If 21xxxxxxxxxxx appears in matrix see TAKT for further instructions on further identification, correct company role and Catalog Number. 'Made By' role should be given to Com-Ser with the DVD-[N] or CD-[N] part of matrix string added in the Catalog Number field.
