What We'll Learn
The different types of disks
What can be stored on various disks
How different disks are used with a computer
Although they all look the same, removable disks come in a variety of formats and can be used to store various types of information.
Although they all are 12 cm in diameter, the picture below shows how different these disks can be:
Common Data Storage Capacity for these disks:
Disks also come in a variety of formats and including "Write Once" or "Read-Write" formats that let you re-use the disk.
A blank disk can be used to store various types of information based on what you hope to use it for.
Audio
CD Audio used for playing in a CD Player
DVD Video
A Movie that will play on a standard DVD Player
Computer Data
Files that can be played or copied to a computer
Unlike a stereo or DVD Player, a computer has the ability to handle all the information types listed above. You can check your CD Player and look for the following labels to see what is supported on your system:
The process of extracting information from a disk can be complex. A computer cannot directly store the Audio format of a CD. The information is "Ripped" from the CD to the computer as follows:
The computer reads an audio track on the CD.
The file is converted to a digital format (usually WMA or MP3)
The file is copied to the Hard Disk Drive
Similarly, when information is copied to a CD, it has to be "Burned".
The computer collects the files in a temporary location
Files are then copied to the CD (if you requested an audio format, they will be converted to tracks as well)
The CD is then closed off, or left open for additional files depending on your settings and format
The CD is verified to make sure all the information was burned correctly
MP3 Players use Data Files. The computer will allow you to copy files to an MP3 Player or Digital Music Player. Usually, this process is called "Syncing" since the computer will make sure that the list of music on the computer is identical to the one on the player, keeping the two lists in sync.
Check your removable disk drive and determine what types of disks are supported on your computer. Keep in mind that if you support Blu-ray, you automatically will be able to handle the lower capacity disks.
