SC-03-02 meeting, New York, 2009-10
Report of the meeting of the SC-03-02 Working Group on Transfer Technologies of the SC-03 Subcommittee on the Preservation and Restoration of Audio Recording in New York, NY., US., 2009-10-10.
The meeting was chaired by the AESSC secretary, M. Yonge, in the absence of any working group officer.
The agenda and the report of previous meeting, held in Munich, 2009-05-08 were accepted as written.
AES-X064 Calibration material, 78 rpm coarse-groove discs
Scope: Production of a limited series of a test record set including a re-edition of the IEC PUB 98 coarse-groove 78-RPM test frequency record and a lateral-cut geometrical and level test calibration record, with adequate technical and historical documentation and instructions for use in calibrating a playback system.
Intent: Information Document
C. Lacinak pointed out that he had been contacted by more than one person who had purchased the AES coarse-groove test disc but were unsure how to use it to get the maximum benefit. He proposed that some guidelines be produced for the benefit of those technicians who were meeting the calibration of playback alignment as a new topic. It was felt that this could be done with minimum formality, and suitable drafts are sought.
AES-X106 Stylus shape and size for transfer of records
Scope: to identify the mechanical part of the interface between a mechanical record and an electrical signal representative of the intended information stored by the mechanical record. The standard will propose a set of guidelines to ensure optimal retrieval of the recorded information in various groove systems used in mechanical recording.
The latest draft, posted by D. Schueller, was edited in the meeting. Proposed changes discussed on the email reflector by Schueller, G. Brock-Nannestad, F. Lechleitner and D. Sbardella were discussed and incorporated into the draft.
In the case of "embossed aluminium discs", it was felt appropriate to include a warning about the damage that could be caused by incorrect stylus choice, although there was no clear consensus on what constituted a "correct" stylus choice - various types were discussed and found to be not universally applicable to this format.
The revised draft was posted to the working group document site after the meeting.
No new liaisons.
No new projects were proposed.
There was no new business.
The next meeting will be scheduled in conjunction with the AES 128th Convention in London, UK., 2010-05
