A hard disk drive (HDD), hard disk, hard drive, or fixed disk, is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small rectangular box.

Digital Linear Tape (DLT; previously called CompacTape) is a magnetic-tape data storage technology developed by Digital Equipment Corporation (DEC) from 1984 onwards. In 1994, the technology was purchased by Quantum Corporation, who manufactured drives and licensed the technology and trademark. A variant with higher capacity is called Super DLT (SDLT). The lower cost "value line" was initially manufactured by Benchmark Storage Innovations under license from Quantum. Quantum acquired Benchmark in 2002.
Linear Tape-Open (LTO) is a magnetic tape data storage technology originally developed in the late 1990s as an open standards alternative to the proprietary magnetic tape formats that were available at the time. Hewlett Packard Enterprise, IBM, and Quantum control the LTO Consortium, which directs development and manages licensing and certification of media and mechanism manufacturers.
Travan is an 8 mm magnetic tape cartridge design developed by the 3M company, used for the storage of data in computer backups and mass storage. Over time, subsequent versions of Travan cartridges and drives have been developed that provide greater data capacity, while retaining the standard 8 mm width and 750' length. Travan is standardized under the QIC body. HP Colorado, Iomega DittoMax and AIWA Bolt are proprietary versions of the Travan format.
Micropolis Corporation was a disk drive company located in Chatsworth, California and founded in 1976. Micropolis initially manufactured high capacity hard-sectored 5.25-inch floppy drives and controllers, later manufacturing hard drives using SCSI and ESDI interfaces.

The company has manufacturing and logistics facilities in the United States, United Kingdom, Ireland, Taiwan, and China.
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. After considering technologies such as wire matrices, rod arrays, drums, drum arrays, etc., the engineers at IBM's San Jose California laboratory invented the hard disk drive. The disk drive created a new level in the computer data hierarchy, then termed Random Access Storage but today known as secondary storage, less expensive and slower than main memory but faster and more expensive than tape drives.
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording.
The Linear Tape File System (LTFS) is a file system that allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives. It requires both a specific format of data on the tape media and software to provide a file system interface to the data.
Tallgrass Technologies Corporation was an American computer hardware company that was the first to offer a hard disk drive product for the IBM PC in 1981. Tallgrass was a Kansas City based microcomputer hardware and software company founded in December 1980 by David M. Allen. The hard disk drive product was initially sold in Computerland stores, alongside the original IBM PC. Tallgrass added tape-backup systems to its product line in 1982.
Dot Hill Systems Corp was a manufacturer of computer storage area network arrays. Providing computer hardware and software products for small and large computer data storage systems. Dot Hill came into being when Box Hill Systems Corp acquired Artecon, Inc. based in Carlsbad, California. BoxHill was already traded on the NYSE as BHSC. After the combined company changed its name to Dot Hill Systems Corp, the symbol changed to HILL. Box Hill sold hardware products with names including the word Box as well as backup software and renamed OEM tape libraries from manufacturers like ATL Odetics and StorageTek. Artecon sold its own selection of drive array products with the additional selling point of being NEBS certified. Around 1998 or 1999, Box Hill had found itself in a difficult position. Its flagship fibre channel product was unable to deliver the features originally intended and had to rely on software raid instead. It performed well mirroring, but fell short otherwise. After the acquisition by Dot Hill, the inevitable merging of products and talent led to the eventual migration of the headquarters to Carlsbad and a shift away from backup and tape products. The resulting changes lead to a large change in workforce as the former Artecon management team took the lead.
CMS Enhancements Inc. was an American computer company headquartered in Irvine, California. Founded in 1983, the company's main product lines in the 1980s were internal and external hard drives and tape drives. The company's hard drives were chiefly sourced from Seagate and reconfigured in bespoke configurations for certain computing platforms, such as the Macintosh, the IBM PC, and the Compaq Deskpro, among others.
