MIL-HDBK-9660 Dod Produced Cd-Rom ProductsThis document was prepared by the Defense information Systems Agency DISA, in cooperation with the services and other activities within the Department of Defense DOD. The goal of this document is to provide information and guidelines to support the creation and interoperability of Compact Disc-Read Only Memory CD-ROM development and use within DOD. This document specifies core compact disc fundamentals for the DOD community. It is strongly recommended all DOD components comply with the fundamentals established within this document. Specialized functions within DOD may require expanded internal guidance to meet their own mission needs. All other Government entities are invited to use this document.

A.7. CD TESTING

Prior to CD-R, testing was only an issue for large disc manufacturing facilities which understood the difficult testing process and could afford the expensive equipment. Testing without special equipment is usually done by "playing" the disc; however, this does not provide a true indication of reliability since in essence you are also testing the player and the computer. A specification for jitter (a measure of the standard deviation of pit length within a window of tolerance) did not exist prior to CD-R because factory replication was performed under optimal conditions and equipment. Since in CD-R the recording layer is not altered by burning a physical hole, a test suite for jitter has since been added to the Red Book Specification.
