Digital Mass Storage Systems (DMMS) – ideal solution for digital audio archiving

• Introduced during 1990s by radio sound archives• Complex and cost intensive (hard and software)

Smaller collections unable to finance DMMS – started digitisation using R-DAT and CD-R as single carrier target formats

• R-DAT threatened by obsolescence• CD-R (DVD-R) presently perhaps the most unsafe

recording medium

Since around 2000• professional computer back-up tape drives and

media• hard disk drives (HDDs)became within affordable reach

Single (or double) operator systems:• High precision stand alone A/D converter• Digital audio workstation (DAW) with sufficient

storage capacity in excess of storage medium• Parallel safety storage space of same capacity• Tape drive - LTO (Ultrium) currently popular

medium: 1st generation 100 GB native/tape2nd generation 200 GB native/tape

• Minimum of two tapes, preferably of different production, to be stored at different locations

Multiple operator, multiple DAW systems• Server (RAID) system with sufficient storage capacity

to accommodate data before transfer to back-up tape• Server also to accommodate MP3 file for browsing

purposes

Problems and perspectives• Data can be lost at any stage without pre-warning• Data integrity checking difficult to implement• Data management highly demanding in absence of

HSM software• Scalable towards DMSS by introducing HSM and a

“juke box” (automated tape library)

Vision: “Personal” DMMSs for applications in all professions in need of storage capacities beyond the general world of offices:

• Audiovisual archives• Architects• Computer graphic designers• Digital photographers
