SC-03-04 meeting, London, 2010-05

Report of the meeting of SC-03-04 Working Group on Storage and Handling of Media of the SC-03 Subcommittee on the Preservation and Restoration of Audio Recording, held in London, UK, 2010-05-24.

The meeting was convened by L. Gaustad on behalf of subcommittee vice-chair D. Schueller

The agenda, and the report of the previous meeting held in Munich, 2005-09-08, were approved as written.

Open projects

AES35-R Review of AES35-2000 (r2005): 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.
Scope: This standard specifies test methods for estimating the storage life expectancy (LE) of information stored on rewritable and write once magneto-optical media. Only the effects of temperature and relative humidity (RH) are considered.

The meeting proposed this document for withdrawal as MO-discs are dead media.

AES38-R Review of AES38-2000 (r2005): 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.
Scope: This standard specifies test methods for estimating the life expectancy of information stored in recordable compact disc systems. Only the effects of temperature and relative humidity on the media are considered.

The standardized life expectancy estimated using this model is defined for discs maintained at 25 degC and 50 % RH. Discs exposed to more severe conditions of temperature and humidity are expected to experience a shorter life. The test plan documented in this standard does not attempt to model degradation due to exposure to light, corrosive gases, contaminants, or mishandling, and variations in the playback subsystem.

The meeting proposed this document for reaffirmation

AES49-R Review of AES49-2005 Magnetic Tape - Care and handling practices for extended usage
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.

The meeting proposed this document for stablisation

Development projects

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

Secretary to contact Peter Adelstein for status on i3a-WG5 JTC.

AES-X145 Care and Handling of Optical Discs
Scope: This standard concerns the care and handling of digital optical discs during use. It addresses the issues of physicalintegrity 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

Action: The meeting proposed to withdraw this project

AES-X153 Care and handling of magnetic hard disc drives
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.

Status: Awaiting JTC input

Liaisons:

There were no other liaison issues.

New Projects:

No new projects

New business:

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.
