Abstract

Optical disk technology (CD-ROM etc.) is a new and secondary storage technology. Optical disks have immense capacities and very fast retrieval performance; they are also rugged and have very long storage lifetimes. These characteristics are making them a serious threat to the traditional dominance of magnetic disks. It is important to understand and study this young and significant technology and to design retrieval structures that best utilize characteristics. Presents 6 file systems (Write-Once B-Tree; Time Split B-Tree; Compact Disk File System; Optical File Cabinet; Buffered Hashing; BIM Trees
