Term
Microdrives
Definition
True hard drives, using platters and read/write heads that fit into the tiny CF form factor. They are slower and use more power than flash drives.
Term
Secure Digital (SD) Cards
Definition
The most common flash media format today. It comes in two smaller forms called MiniSD and MicroSD.
Term
Standard SD
Definition
One of the three SD card storage capacities that stores from 4MB to 4 GB.
Term
Secure Digital High Capacity (SDHC)
Definition
One of the three SD card storage capacities that stores from 4GB to 32GB.
Term
Secure Digital Extended Capacity (SDXC)
Definition
One of the three SD card storage capacities that stores from 32Gb to 2TB.
Term
Memory Stick
Definition
Flash memory used mainly by Sony and has several formats including Standard, Pro, Duo, Pro Duo, and Micro.
Term
Extreme Digital (XD) Picture Cards
Definition
Flash memory that is almost exclusively used in Olympus and Fujifilm digital cameras. This type of flash memory comes in three flavors: original, Standard (Type M), and Hi-Speed (Type H).
Term
Card Reader
Definition
Used to access the data on every type of flash memory.
Term
Optical Disk
Definition
The generic term for all the different types of shiny, 12cm wide discs such as CD, DVD, and Blu-ray Discs.
Term
Compact Disc (CD)

One of the types of optical discs that eliminated VHS cassette tapes from the commercial home movie market and has also grown into a contender for backups and high-capacity storage. This optical disc uses smaller pits than CDs, comes in both single-sided  (SS) and double-sided (DS) formats, and comes in single-layer (SL) and dual-layer (DL) formats.
Term
Blu-Ray Disc (BD)
Definition
One of the types of optical discs that eliminated the High-Definition DVD (HD DVD) format to become the only high-definition and high-capacity optical format. This optical disc has storage capacity of up to 25 GB (single-layer disc) and 50 GB (dual-layer disc). They come in two physical sizes: standard and mini.
Term
Lands
Definition
Non-pitted spots on a CD.
Term
CD-Digital Audio (CDDA)
Definition
A special CD format that divides the CD's data into variable-length tracks; on music CDs, each song gets one track. It is an excellent way to store music, but is a horrible way to store data because it lacks any error checking, file support, or directory structure.
Term

Definition
This CD format divides the CD into fixed sectors, each holding 2353 bytes.
Term
ISO-9660 or CD File System (CDFS)

Definition
CD discs that enable CD-Burners to add (burn) data to  them. They came in two varieties: a 74-minute disc that holds approximately 650 MB, and an 80-minute variety that holds approximately 700 MB. Once data was burned onto the disc, the data can't be erased or changed.
Term
Multisession Drives
Definition
A CD-R drive that allows multiple burn sessions so you can go back and burn additional data onto the CD-R disc until the disc is full. These drives can also "close" a partially filled CD-R so that no more data can be burned onto that disc.
Term
CD-Rewritable (CD-RW) Drives
Definition
This type of drive replaced CD-R drives. It enables you not only to burn disc, but to burn over existing data on a CD-RW disc.
Term
Universal Data Format (UDF)
Definition
The file format that replaced ISO-9660, resulting in a single file format that any drive and operating system can read. It supports a feature called Mount Rainier or packet writing, which works with it so you can copy individual files back and forth like a hard drive.

Term
DVD-ROM
Definition
This stores up to almost 16 GB of data and is the equivalent of the standard CD-ROM data format.
Term
BD-ROM
Definition
The equivalent of the standard DVD-ROM data format except it can store much more data and produces superior audio and video results.
Term
ISO File
Definition
A complete copy of an optical disc.
Term
Region Code
Definition
Encoding that enables you to play those movies only on a player that shares the same code.
Term
Buffer RAM or Buffer
Definition
It stores the incoming data from the recording source. Every CD, DVD, and Blu-ray disc burner comes with it onboard.
Term
Buffer Underrun
