MIL-HDBK-9660B
Ultimedia Services, an optional package of multimedia tools. Photo-CDs use some of the Green Book specifications, but are recorded under the Orange Book, Part II, which defines CD-WO appendable media.
kk. Pixel - Short for Picture Element, the smallest addressable element of a computer graphic display area into which a document is divided for scanning purposes.
ll. Premastering Software - Software used to prepare information for the proper format to be physically recorded on a CD. The three essential functions of premastering software are: to convert the file structures into the standardized file format of ISO 9660 and create a disc image on a computer's hard disk, simulate the disc image as a CD-ROM, and send the CD-ROM image to the CD recorder. It may also be able to image the CD-ROM "on-the-fly" while sending it to the recorder; however, using this eliminates the ability to simulate the CD on the hard disk.
mm. Producing Organization - The name of the Government organization with overall responsibility for the product.
nn. Red Book - This book specifies the sector and track structure and layout for an audio compact disc. The CD industry started when Philips and Sony introduced the Compact Disc Digital Audio (CD-DA or CD-A) standard. Virtually all music CDs conform to this standard.
oo. SCI - Sensitive Compartmented Information. Information and material that requires special controls for restricted handling within compartmented intelligence systems and for which compartmentation is established. See DOD Directive 5200.1-R, Information Security Program.
pp. SCSI - Small Computer Systems Interface is an interface specification for connecting multiple peripheral equipment to computers. It is utilized on most Unix & Macintosh platforms and is readily available on PC based platforms and CD devices.
qq. SCSI-2 - Defines the actual SCSI connection, termination, and data transmission in more detail then the original SCSI specification. Several multi-platform computer peripherals including CD- ROM drives, CD-Recordable drives, and image scanners use SCSI-2 interfaces.
rr. TAFIM - Technical Architecture Framework for Information Management. A DOD publication which provides guidance for the evolution of the DOD technical infrastructure. It consists of eight volumes, providing services, standards, design concepts, components, and configurations that can be used to guide the development of technical architectures that meet specific mission requirements.
ss. Track-At-Once - A form of incremental writing, most used by CD recorders today. The data or audio tracks are written first, then the lead-in, followed by the lead-out. Updates are possible, and tracks of data may be recorded one at a time, or as multiple tracks in one uninterrupted stream (limit of
99 tracks), but the disk cannot be read by a standard CD-ROM drive (that cannot find data on a partially filled disk) until it has been "finalized." Finalizing means writing the lead-out and the Table of Contents (TOC) on the disk. No updates may be added after a disk has been finalized. After finalization, the disc essentially contains one session. When the laser turns off between writes, a "link block" is written of about 600 KB (therefore, if you use all 99 tracks, about 60 MB of disc space is wasted). A link block is nothing more than a null sector where the drive stopped writing and where it will start again when another track is written. Such blocks present no problems to CD-ROM or CD-A players, which ignore them. However, if used as a master CD, sometimes the link blocks show up as "E32" uncorrectable errors to
the sophisticated mastering machines at replication factories.
