W18 - THE REPLAY OF HISTORICAL MAGNETIC TAPE—MORE THAN PRESSING THE PLAY BUTTON

Chair:
Dietrich Schüller, Phonogrammarchiv Vienna
Panelists:
Friedrich Engel, Magnetic Recording Historian
Alexander Füller, Replay Practitioner, Phonogrammarchiv Vienna
Bernhard Graf, Replay Practitioner, Phonogrammarchiv Vienna
Nadja Wallaszkovits, Chief Technician Audio, Phonogrammarchiv Vienna

Abstract:
Since analog magnetic tape technology is no longer a part of the audio production process, specific knowledge is endangered to decline. The workshop discusses the various problems occurring in the transfer process of historical magnetic audio tapes. Basing on a definition of historical tape brands and an overview of early magnetic tape developments, the practical handling of critical tapes is outlined.

Starting with the analysis of the physical and chemical preservation status of the individual tape, the choice and adjustment of the replay equipment and parameters are discussed. Problems of carrier handling and physical restoration are demonstrated, as well as possible signal enhancement on the playback process only. The workshop focuses on a practical demonstration of handling and reproduction of original tapes from the early ages of magnetic recording, stored under irregular conditions.
