ABSTRACT

Optical  disks,  due to the low storage cost per bit of
stored  information,  easy  replication,  large storage
capacity,  and long archival life,  are projected to be
the   dominant  storage  technology  for  many  storage
intensive applications.

In  the  research  presented we investigate the various
types  of  available  optical  disk storage systems and
through  experimentation  we identify their performance
characteristics.

Based  on the experimental results, mathematical models
capturing  the  behavior  of  these  systems  have been
developed and validated against the actual systems they
represent.   These   models  are  incorporated  in  the
implementation  of  simulators for various optical disk
storage systems.

We  investigate the effects of a new notion of blocking
and  we  show that in certain application environments,
it  can  improve  the  retrieval performance of optical
disk storage systems.

Optical   disk  storage  media  is  new  and  not  well
understood. The research presented provides answers and
new  insights  about  the  various optical disk storage
architectures and models their access performance.
