Title: Optical disk driving device
Inventor: YOSHIMOTO KYOSUKE
IPC: G11B7/007
Filed: 2000-01-04
Abstract: PROBLEM TO BE SOLVED: To make simply and quickly obtainable physical positions and to expand the application of an optical disk by constituting the recording area of the optical disk with logical tracks consisting of a fixed number of sectors and rewriting recording attributes of the respective zones recorded in a management table. SOLUTION: Each physical track is divided into plural pieces of sectors. Plural lines of the physical tracks are collected to form zones. A logical track is constituted of plural piece of sectors. Since track addresses and sector addresses written in header parts of an optical disk 2 correspond to linear addresses from a host device 32 as they are, an actual logical track address and an actual logical sector address can be calculated with a simple integer operation. When the optical disk 2 whose whole surfaces are produced as R/W areas is used and attributes of respective zones on a management table 41 are changed into WOs and data are written in the changed areas, rewritings can not be performed, that is, these parts become ROMs.
