Overview
ISO 18938:2014 - Imaging materials - Optical discs - Care and handling for extended storage - defines general principles and recommendations for the care and handling of digital optical discs to preserve access to recorded data over extended storage lifetimes. The standard addresses physical integrity, environmental controls, contamination control, inspection, cleaning and maintenance, transportation, disaster response, and staff training to maximize disc longevity and data integrity.
Key topics
ISO 18938:2014 covers practical, technical topics and requirements for optical disc preservation, including:
- Disc composition and failure mechanisms - descriptions of substrate, data, reflective and protective layers and how mechanical, chemical or environmental stress can cause degradation.
- Use and handling environments - guidance on pollutants, temperature and humidity management, light exposure, air quality and vibration to reduce data loss risk.
- Contamination and cleaning - identification of contaminants (fingerprints, dust, solvents), recommended cleaning methods, compatible solvents and maintenance frequency.
- Inspection and monitoring - procedures for visual inspection and error-rate monitoring to detect early signs of degradation.
- Identification and labeling - safe labeling practices (adhesive labels vs printing, thermal and inkjet methods) to avoid damage.
- Transportation and storage - packaging, enclosures and shipping practices to protect discs from mechanical and environmental exposure.
- Disaster preparedness and response - procedures for water, fire and post-disaster recovery, including wet- and dry-disc handling and repair considerations.
- Staff training and checklists - required training content, update schedules and a practical minimum handling checklist for routine operations.
Applications
ISO 18938 is practical for organizations that need reliable long-term access to optical media:
- Archival storage and digital preservation - libraries, museums, national archives and cultural heritage institutions preserving optical media.
- Media and data centers - IT managers and records managers maintaining optical backups or master files.
- Film, photography, and imaging houses - custodians of imaging collections stored on CDs, DVDs or optical data discs.
- Disaster recovery planning - teams responsible for post-disaster retrieval and restoration of optical media.
The standard helps reduce data loss through improved disc care, cleaning, storage environment control, and staff procedures.
Who should use this standard
- Archivists, conservators, and collection managers
- Records managers and IT backup administrators
- Museum and library preservation staff
- Facilities and logistics teams handling media transport
- Disaster recovery and risk management personnel
