The meeting was convened by chair T. Sheldon.
The agenda and the report of the previous meeting held in Amsterdam, Netherlands, 2003-03-23 were approved as distributed.
AES28-R: Review of AES28-1997 (r2003): AES standard for audio preservation and restoration - Method for estimating life expectancy of compact discs (CD-ROM), based on effects of temperature and relative humidity.
This standard was reaffirmed in 2003. No comments have been received subsequent to reaffirmation. No action is needed at this time. The status of this standard remains unchanged.
AES35-R: Review of AES35-2000: AES standard for audio preservation and restoration -- Method for estimating life expectancy of magneto-optical (M-O) discs, based on effects of temperature and relative humidity.
This standard is due for mandatory review in 2005. Unless the AES/I3A Joint Technical Committee takes action to revise the document earlier, the working group expects to recommend reaffirmation by 2004-05.
AES38-R: Review of AES38-2000: AES standard for audio preservation and restoration -- Life expectancy of information stored in recordable compact disc systems -- Method for estimating, based on effects of temperature and relative humidity.
This standard is due for mandatory review in 2005. Unless the AES/I3A Joint Technical Committee takes action to revise the document earlier, the working group expects to recommend reaffirmation by 2004-05.
AES-X55: Projection of the Life Expectancy of Magnetic Tape.
This project has yet to yield supportable scientific approaches to achieve the goal of measuring the life expectancy of magnetic tape. Several avenues of possibility remain open in the minds of working group members. The project remains active.
AES-X80: Liaison with AES/I3A-TG5-WG5 Joint Technical Committee (JTC)
This liaison is active and productive, with many AESSC members participating and many valuable standards and recommended practices produced and being written.
1. Care and handling of optical discs. This document is currently being drafted by the AES/I3A Joint Technical Commission as a part of the AES-X80 liaison. The proposed standard would be a companion of the standard of care and handling of magnetic tape (see AES-X54, above). The working group unanimously agreed to proceed with this new work item. Sheldon will submit a proposal by 2003-12.
2. Extended term storage environment for multiple media archives. In recent years, standards and recommended practices have been published for a variety of media that carry audio content as well as other forms of content (e.g., still image, moving image, data). These various standards and recommended practices call for different temperature and humidity storage environments and assume the ability of archive to segregate media types into specific storage environments. This new work item seeks to establish a single storage environment definition for multi-media facilities. The working group agreed unanimously to proceed with this new work item for audio stored in multimedia environments. Sheldon will submit a proposal by 2003-12
The next meeting is scheduled to coincide with the AES 116th convention in Berlin, Germany, 2004-05.
