Intent: Review, Initiated: 2005, Target: 2010
Current goal: Status report, Goal date: Continuing

No action was requested or required.

AES49-R: Review of AES49-2005 Magnetic Tape - Care and handling practices for extended usage
Project scope: This standard concerns the care and handling of magnetic recording tape during use. It addresses the issues of physical integrity of the medium necessary to preserve access to the audio or other data (information) recorded on the tape. This standard recommends handling procedures to maximize the effective life of magnetic tape.

Intent: Review, Initiated: 2005, Target: 2010
Current goal: Status report, Goal date: Continuing

No action was requested or required

AES-11id-R: Review of AES-11id-2006, AES Information document for Preservation of audio recordings - Extended term storage environment for multiple media archives
Project scope: This information document provides suggested guidelines for four extended-term storage environments for archives that contain a variety of recording media, based on the corresponding ISO storage standards for those media. Whenever possible, the storage environments in the ISO storage standards should be followed. This technical report does not replace these ISO storage standards. In addition to environment recommendations, those standards also include other vital information pertinent for the long-term keeping of recording materials such as inspection, housing, and handling guidelines.

Intent: Review, Initiated: 2006, Target: 2011
Current goal: Status report, Goal date: Continuing

No action was requested or required

Development Projects

AES-X080: Liaison with AES/ i3a-WG5 Joint Technical Committee (JTC)
Project scope: to formalize the working relationship between AESSC SC-03 and International Imaging Industry Association (i3a) WG5.

Intent: Liaison, Initiated: 1998, Target: Continuing
Current goal: Status report, Goal date: Continuing

No comment was made.

AES-X145: Care and Handling of Optical Discs
Project scope: This standard concerns the care and handling of digital optical discs during use. It addresses the issues of physical integrity of the medium necessary to preserve access to the recorded data (information). Included are recommendations for handling procedures to maximize the effective life of optical discs. This standard addresses the following subjects: a) use and handling environments, including pollutants, temperature and humidity, light exposure and magnetic fields; b) contamination concerns; c) inspection; d) cleaning and maintenance, including cleaning methods and frequency; e) transportation; f) disasters, including water, fire, construction and post-disaster procedures; g) staff training.

Intent: Standard, Initiated: 2004-09-09, Target: 2007
Current goal: PCFC, Goal date: 2009-10

JTC draft will be edited and posted by the Standards Manager

AES-X153: Care and handling of magnetic hard disc drives
Project scope: To establish care, handling, and storage standards for high capacity magnetic hard drives. The document will include life expectancy assessment, effects of temperature cycling, proper use of the mechanical drives holding the media.

Intent: Standard, Initiated: 2004-11-19, Target: 2008
Current goal: PTD, Goal date: 2009-10

Awaiting JTC input.

Liaisons

There were no other liaison issues.

New Projects

No new projects were received or proposed.

In the context of AES-X153 it was debated that a similar document for flash cards, SD cards, etc. would be useful, as such carriers have gained considerable importantce in the gathering of audio data (location recording) as well as EPROMS, because of their importance for the function of various audio equipment. However, no formal decision to establish a new project was made.

New business

There was no new business.

The next meeting will scheduled in conjunction with the AES 127th Convention in New York, NY., US., 2009-10
