Secondly, even if the storage media discontinue production. The authors have had a range of themselves are reliable, the devices used to read such experience re-working performances over a number of years, media share the same risks of obsolescence as the device including compositions by Luigi Nono and Jonathan Harvey, amongst others. In this paper we look at the problem as a – either the device itself is required (e.g. for a Yamaha whole, focusing on Jonathan Harvey’s works with electronic data cartridge), or a dedicated media reader. Various elements, which span some twenty-six years, as exemplars of generic digital data media formats have come and gone, the types of problems involved. including 5.250 floppy disks, Syquest removable car- tridges, and 2.80 Quick Disks; 3.50 floppy disks are increasingly rare, and Zip disks have rapidly reduced in 1.

Such works are not performance, having been involved in the presentation captured effectively by stereo recordings, or even of many works with live electronics over a number of necessarily by increasingly common surround sound years. As such we are interested in the archived materials formats. As well as performance problems, there are that publishers have available for hire, as well as the those related to archiving works, since sets of parameter realisation of works based on those materials.
