Performance optimizations for optical disc architectures
Daniel Alexander Ford · 1992
Optical disc technology is a new promising secondary storage technology for the computer industry. Many features of this new technology are not compatible with the more mature magnetic disk storage technology. In order to develop software that utilizes this new disc technology effectively we should understand and abstract (model) its important characteristics as well as develop algorithms that make good use of these characteristics. The contributions of this thesis are: a model of the unusual access characteristics of optical discs and a retrieval performance analysis based on this model; a new file organization for optical discs and an analysis of a trade-off between retrieval performance and disc space consumption for WORM optical discs using this new file organization; and a solution to the problem of the optimal placement of data on CLV format optical discs.
