Abstract
An optical recording system separates and records data on optical disks that are loaded on respective optical disk drives. On each optional disk, information identifying the disk is recorded so that the optical disk may be loaded arbitrarily into any of the optical disk drives. Each optical disk may also include check symbols for data that are recorded to enable data on defective optical disk to be properly reproduced.
