It demonstrated a significant advance in technology, allowing an increase in recording density to 300 tracks per inch and 5600 bits per inch. In 1953, IBM recognized the immediate application for what it termed a "Random Access File" having high capacity and rapid random access at a relatively low cost. Other words that entered English at around . The term for hard disk drive. It featured a smaller, lighter read/write head that was designed to ride on an air film only 18 millionths of an inch thick. Since 1995, more than 100 tech experts and researchers have kept Webopedias definitions, articles, and study guides up to date. - The contamination-free environment allows Winchester disks to employ much greater precision of data recording and accessing, resulting in greater density of data storage than the interchangeable disk packs. Its primary distinguishing feature was that the disk heads were not withdrawn completely from the stack of disk platters when the drive was powered down. In 1998 Macintosh introduced its new computer, the IMAC, without a floppy disk drive. The capacity of hard drives has grown exponentially over time. Bellis, Mary.
