Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
105 words
In an optical recording system having a plurality of optical disk drives, wherein each optical disk drive is loaded with a respective optical disk, and each optical disk having a like sequence of physical addresses an optical recording method, comprising the steps of: recording a first piece of data in a set of data on a first physical address of an optical disk of a first optical disk drive; recording each subsequent piece of data in the set of data on a next sequential physical address, on a successive optical disk drive, in accordance with a predetermined sequence of physical addresses and optical disk drives.
Claim 2
Dependent Claim
105 words
In an optical recording system having a plurality of optical disk drives, wherein each optical disk drive is loaded with a respective optical disk, and each optical disk having a like sequence of physical addresses an optical recording method, comprising the steps of: recording a first piece of data in a set of data on a first physical address of an optical disk of a first optical disk drive; recording each subsequent piece of data in the set of data on a next sequential physical address, on a successive optical disk drive, in accordance with a predetermined sequence of physical addresses and optical disk drives.
Claim 3
Dependent Claim
27 words
An optical recording method in accordance with claim 1, wherein the rotary phase of each optical disk drive is sequentially shifted by at least one physical address.
Claim 4
Dependent Claim
39 words
An optical recording method in accordance with claim 1, wherein the time between recording performed by each optical disk drive is delayed by a sufficient time for rotation of a predetermined number of physical addresses of an optical disk.
