SC-03-02 meeting, London, 2010-05
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 London, UK, 2010-05-25
The meeting was convened by chair L. Gaustad.
The agenda and the report of previous meeting, held in New York, 2009-10-10 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.
Assigned to: SC-03-02, Initiated: 2007
Intent: Information document, Target: 2012
Current goal: Status report, Goal date: 2010-05
Status: The metal master that was used for the test disc was never presses in shellac. This causes problems in producing a replay correction curve caused by the difference in compliance between the materials.
Action point: Locate an existing shellac test record, locate the corresponding metal matrice, press this matrice in the vinyl used for the AES-X064 discs, replay and define correction, finance by sponsorship.
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.
Assigned to: SC-03-02, Initiated: 2000-02
Intent: Information Document, Target: 2008
Current goal: PWD, Goal date: 2009-12
Status: Draft discussed and revised; Sec to format and CFC
Discussion: The proposed PWD by Gaustad on March the 1th this year, were corrected in terms of language inaccuracies, and will be forwarded for CFC. It is already uploaded to the reflector site with the file name X106_pwd_final_20100525.doc
There were no other liaison issues.
The question of producing a micro-groove test disk set was discussed and it was decided to make a budget for such a project, prior to initialising it.
There was no new business.
The next meeting will be scheduled in conjunction with the AES 129th Convention in San Francisco, CA., US, 2010-11.
