Main Page | See live article | Alphabetical index MD Data is a minidisc for storing computer data. Sony wanted MD Data to replace floppy disks. The technology provided 140 MB of data storage, but it was slow and expensive. Also, data drives can only read or write audio MDs when set in "play" mode, which, however, does not provide computer access to the data. MD Data appears in products such as MD still camera and MD document scanner. This article is from Wikipedia. All text is available under the terms of the GNU Free Documentation License.
