Minidiscs (MDs) are used to store data in compressed digital format. They are made up of a hard cartridge containing a small storage disc, which can be blank or pre-mastered. They have a capacity of 140 megabytes, amounting to about 80 minutes of compressed audio. Audio minidiscs are usually played on portable minidisc players.
Although initially designed for music, minidiscs can also be used for general-purpose storage. Modern minidiscs are available in recordable and multitrack types and capacities of 60, 74, and 80 minutes. They can also connect to a computer’s USB port for decompressing or audio editing.
Player compatibility: Choose a minidisc that can be recognized by most player types. Premastered MDs are usually programmed for universal compatibility, but newer recordable MDs may not be read by older players or recorders.
Anti-skip: If you are buying an MD to use with a portable MD player, make sure it has anti-skip features to keep sounds flowing smoothly as you move. Look for one with a high buffer to prevent interruptions and fragmentation.
Power supply: Choose a minidisk that can run on both AC and battery power. Most manufacturers recommend recording on AC power and using batteries for backup. This will protect the disc and recorder from abrupt stops in case of power failures.
