Strictly speaking, "drive" refers to a device distinct from its medium, such as a tape drive and its tape, or a floppy disk drive and its floppy disk. Early HDDs had removable media; however, an HDD today is typically a sealed unit (except for a filtered vent hole to equalize air pressure) with fixed media.</p> <p>Originally, the term "hard" was temporary slang, substituting "hard" for "rigid", before these drives had an established and universally-agreed-upon name. A HDD is a rigid-disk drive although it is rarely referred to as such. By way of comparison, a so-called "floppy" drive (more formally, a diskette drive) has a disc that is flexible. Some time ago, IBM's internal company term for a HDD was "file".<sup class="noprint Template-Fact"><span title="This claim needs references to reliable sources since June 2008" style="white-space: nowrap;"><i><a href="http://en.wikipedia.org/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><br /></a></i></span></sup></p> <p>HDDs (introduced in 1956 as data storage for an IBM <a href="http://en.wikipedia.org/wiki/Accounting" title="Accounting" class="mw-redirect">accounting</a> computer<sup id="cite_ref-2" class="reference"><a href="http://en.wikipedia.org/wiki/Harddisk#cite_note-2" title="">[3]</a></sup>) were originally developed for use with general purpose <a href="http://en.wikipedia.org/wiki/Computer" title="Computer">computers</a>; see <a href="http://en.wikipedia.org/wiki/History_of_hard_disk_drives" title="History of hard disk drives">History of hard disk drives</a>.</p> <p>In the 21st century, applications for HDDs have expanded to include <a href="http://en.wikipedia.org/wiki/Digital_video_recorder" title="Digital video recorder">digital video recorders</a>, <a href="http://en.wikipedia.org/wiki/Digital_audio_player" title="Digital audio player">digital audio players</a>, <a href="http://en.wikipedia.org/wiki/Personal_digital_assistant" title="Personal digital assistant">personal digital assistants</a>, <a href="http://en.wikipedia.org/wiki/Digital_camera" title="Digital camera">digital cameras</a> and <a href="http://en.wikipedia.org/wiki/Video_game_console" title="Video game console">video game consoles</a>.
