This chapter focuses on the most popular areas and you will find that other devices are similar to install and troubleshoot.Multimedia devices:–CD and DVD technologies–Sound cards–Speakers–Cameras8-4CD Drive OverviewCD Drive terms:–CD Drive also known as a CD-ROM (Compact Disk-Read Only Memory) Drive is a device that uses compact disks.–CD (Compact Disk) is a disk that holds large amounts of data (628MB and higher), such as audio, software applications, and graphics.8-5CD Drive SpeedsCD-ROM drives operate much slower than hard drives.CD-ROM drive specifications:–Average Seek Time is the time required for a drive to move randomly about the disk.–Average Access Time is the time required to find and retrieve data on a disk or in memory.8-6CD Drive SpeedsMultimedia – Table 8.1CD drive transfer speeds8-7CD Drive SpeedsMultimedia – Table 8.2CD drive access times8-8CD Drive Buffers/CacheWays to reduce CD data transfers time:–Buffer memory located on the CD drive–A minimum of 500KB buffer size is recommended8-9Theory of CD Drive OperationData is stored on a CD with pits and flats.–Pits are indentations along the track of a CD.–Flats are lands that separate the pits in a CD.8-10Theory of CD Drive OperationInside a CD driveMultimedia – Figure 8.28-11CD Disk LoadingMethods for inserting a compact disk into a CD drive:–Tray Loaded is a method to insert a CD into a drive. They are less expensive but more likely to have lower MTBFs.MTBF (Mean Time Between Failures) is the average number of hours before a device fails.–Caddy Loaded is a term used to describe how a CD inserts into a CD drive using a special holder.Caddy is a holder for a compact disk that inserts into the CD drive.–Slot Loaded is a term used to describe how a CD loads into a slot in the CD drive. This has the disadvantage of disk jams.8-12CD-ROM Disk LoadingMultimedia – Figure 8.3CD drive with tray and CD caddy8-13CD-R and CD-RWCD-R (compact disk recordable) is a CD drive that can create a compact disk by writing once to the disk.–UDF (Universal Disk Format) is a CD-R drive standard used by some manufacturers.–DDCD (Double Density CD) is a CD disk format that extends to 1.3GB. Drives that use this specification can also read regular CDs, CD-R disks, and CD-RW disks.WORM (Write Once-Read Many) is a technology that writes data once to a disk.8-14CD-R and CD-RWCD-RW (CD rewritable) or CD-E is a CD drive that can write data multiple times to a particular disk.–Dye-Polymer is a technology for making CD-E or CD-RW disks by laser-heating the disk surface to produce light reflecting bumps.MultiRead or MultiRead2 is an OSTA specification that states the CD-RW drive is backward compatible with CD-ROM and CD-R disks.Multisession – A feature which allows a CD-R or CD-RW drive to support multiple sessions.MRW - named Mount Rainier. MRW provides an improvement on UDF by saving to CD and DVDs as if they were hard drives.8-15CD StandardsMultimedia – Table 8.3CD Standards8-16Magneto-Optical DrivesMO (Magneto-Optical) Drive is a type of drive that uses a special technology for reading and writing multiple times to a compact disk. After the disk is heated by the laser to produce a bump, a magnet applies a charge to the surface.8-17DVD DrivesDVD-ROM is a technology that produces disks with superior audio and video performance and increased storage capacity.–In DVD drives, the MPEG-2 video must be converted, and the decoder is the way to convert the data.–DirectX is a Microsoft DVD technology that integrates multimedia drivers, application code, and 3-D support for audio and video.–Region Code is a setting on a DVD drive or disk that specifies a geographic region.8-18DecodersDecoders are used to decompress the video and audio from a DVD.–Hardware Decoder requires a PCI adapter and handles the decoding.–Software Decoder is a type of DVD decoder that puts the burden on the CPU to decode and uncompress the MPEG-2 video data from the DVD.8-19DVD DrivesMultimedia – Table 8.5DVD Region Codes8-20Other DVD TechnologiesTypes of DVD Technologies:–DVD-RAM uses a phase technology like CD-RW and allows data to be rewritten on a DVD-RAM disk.–DVD-R uses WORM technology to use one or two sides of the disk. –DVD-RW (DVD-ReWritable) uses 4.7GB disks that can be erased and rewritten to the disk.–DVD+RW (DVD Read and Write) is a drive that can be read from, written to, and discs holds 2.8GB per side.8-21DVD StandardsMultimedia – Table 8.6DVD book type field values8-22Blu-ray DrivesBlu-ray – an optical disc technology that uses blue laser technology instead of the red laser technology currently used by CD/DVD drives. Blu-ray has a higher data transfer rate than DVDs and stores 27GB on a single side disc or 50GB on a dual-side disc. Blu-ray was developed for high-definition video and data storage.8-23CD/DVD Drive Interfaces and ConnectionsTypes of CD and DVD Drive Interfaces:–PATA–IDE – most common for internal–SATA IDE–SCSI–USB – most
