1 digital video disk
"A form of storage characterized by high capacity (roughly 650 MB) and the use of laser optics rather than magnetic means for reading data. Optical disk storage commonly used for audio, video, and computer data. DVDs range in capacity from 4.7 GB to 17 GB, and can store significantly more than a CD-ROM." -

4 CD-ROM drive
"An electromechancial device that reads data on CD-ROMs. Most CD-ROM drives have a SCSI interface, although some are connected to a PC via a controller for a disk drive. Data is read through a small laser that is focused on the surface of the CD-ROM through optical mirrors in the read/write head. A spindle and drive motor revolve the CD-ROM, so all data, which is stored in spirals from the center, can be read." -
5 storage subsystem
"A stand-alone hardware appliance that hosts one or more storage devices (such as disk drives, tape drives, optical drives), and is peripheral to the server or servers that control access to it. Storage subsystems are used to create centralized data repositories, while freeing computing and storage resources on servers." -
6 UDF
"A file system defined by the Optical Storage Technology Association (OSTA) that is the successor to the CD-ROM file system (CDFS). UDF is used for removable disk media like DVD, CD, and magneto-optic (MO) disks."
