disk cartridge

disk cartridge An exchangeable disk store, now obsolete, that took the form of an assembly containing a single rigid magnetic disk permanently housed within a protective plastic cover. It was introduced by IBM in 1964. The cartridge, according to its type, could be loaded vertically onto its drive (top-loading), or horizontally from the front (front-loading). Either way the cartridge hub, to which the disk was clamped, centered onto the drive spindle and was magnetically clamped. The cover contained apertures to allow fixing of the cartridge to the drive, and a door that the drive opened to allow insertion of the magnetic heads. Once loaded, the disk could rotate clear of the covers. Disk cartridges had storage capacities up to 50 megabytes, depending on track density, bit density, and disk size.

Similar cartridges are used for optical disks, with capacities from a few hundred megabytes to several gigabytes. In some cases the disk is extracted mechanically from the cartridge for use, rather than rotated within it.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
