magentic tape
Fritz Pfleumer, a German engineer, patented magnetic tape in 1928. He based his invention off Vlademar Poulsen's magnetic wire. -
Magnetic Drum
G. Taushek, an Austrian innovator, invented the magnetic drum in 1932. He based his invention off a discovery credited to Fritz Pfleumer. -
Williams tube
Professor Fredrick C. Williams and his colleagues developed the first random access computer memory at the University of Manchester located in the United Kingdom. He used a series of electrostatic cathode-ray tubes for digital storage. A storage of 1024 bits of information was successfully implemented in 1948. -
selectron tube
The Radio Corporation of America (RCA) developed the Selectron tube, an early form of computer memory, which resembled the Williams-Kilburn design. -
delay line memory
he delay line memory consists of imparting an information pattern into a delay path. A closed loop forms to allow for the recirculation of information if the end of the delay path connects to the beginning through amplifying and time circuits. -
magnetic core
A magnetic core memory, also known as a ferrite-core memory, uses small magnetic rings made of ceramic to store information from the polarity to the magnetic field it contains. -
Hard disk
hard disk implements rotating platters, which stores and retrieves bits of digital information from a flat magnetic surface. -
music tape
Philips introduced the compact audio cassette in 1963. Philips originally intended to use the audio cassette for dictation machines however, it became a popular method for distributing prerecorded music. -
DRAM (PDF)
Robert H. Dennard invented DRAM cells. Dynamic Random Access Memory technology (DRAM), or memory cells that contained one transistor. DRAM cells store bits of information as an electrical charge in a circuit. DRAM cells increased overall memory density. -
Twister memory
Bell Labs developed Twistor memory by wrapping magnetic tape around a wire that conducts electrical current. -
Twister Memory
Bell Labs developed Twister memory by wrapping magnetic tape around a wire that conducts electrical current. -
Bubble Memory
Andrew Bobeck invented the Bubble Memory, a thin magnetic film used to store one bit of data in small magnetized areas that look like bubbles. -
8" Floppy
IBM started its development of an inexpensive system geared towards loading microcode into the System/370 mainframes. As a result, the 8-inch floppy emerged. A floppy disk, a portable storage device made of magnetic film encased in plastic, made it easier and faster to store data. -
5.25" floppy
Allan Shugart developed a smaller floppy disk, because the 8-inch floppy was too large for standard desktop computers. The 5.25-inch floppy disk had a storage capacity of 110 kilobytes. The 5.25-inch floppy disks were a cheaper and faster alternative to its predecessor. -
CD
James T. Russel thought of using light to record and replay music. As a result, he invented the optical digital television recording and playback television in 1970; however, nobody took to his invention. -
3.5" floppy
The 3.5-inch floppy disk had significant advantages over its predecessors. It had a rigid metal cover that made it harder to damage the magnetic film inside. -
CD ROM
The CD-ROM, also known as the Compact Disk Read-Only Memory, used the same physical format as the audio compact disks to store digital data. The CD-ROM encodes tiny pits of digital data into the lower surface of the plastic disc, which allowed for larger amounts of data to be stored. -
DAT
Sony introduced the Digital Audio Tape (DAT), a signal recording and playback machine. It resembled the audio cassette tape on the surface with a 4 millimeter magnetic tape enclosed into a protective shell. -
DDS
Sony and Hewlett Packard introduced the Digital Data Storage (DDS) format to store and back up computer data on magnetic tape. The Digital Data Storage (DDS) format evolved from Digital Audio Tape (DAT) technology. -
MOD(PDF)
The Magneto-Optical disc emerged onto the information technology field in 1990. This optical disc format used a combination of optical and magnetic technologies to store and retrieve digital data. A special magneto-optical drive is necessary to retrieve the data stored on these 3.5 to 5.25-inch discs. -
MiniDics
The MiniDisc stored any kind of digital data; however, it was predominately used for audio. -
DLT(PDF)
An alternative to magnetic tape used in computer storage -
Zip
Became commonly used in 1994 to store digital files. It was a removable disk storage system introduced by Lomega. -
Compact Flash
Used flash memory in an enclosed disc to save digital data. CF devices are used in digital cameras and computers to store digital information. -
DVD
The next generation of digital disc storage. DVD, a bigger and faster alternative to the compact disc, serves to store multimedia data. -
Smart media
a flash memory card, in the summer of 1995 to compete with Mini-card and San-disk. -
CD-RW
The Compact Disc Rewritable disc, a rewritable version of the CD-ROM, allows users to record digital data over previous data. -
Multimedia Card
The Multimedia Card (MMC) uses a flash memory card standard to house digital data. -
Microdrive
A USB Flash Drive uses a NAND-type flash memory to store digital data. A USB Flash Drive plugs into the USP interface on standard computers. -
SD Card
The Secure Digital (SD) flash memory format incorporates DRM encryption features that allow for faster file transfers. -
Blu Ray
the next generation of optical disc format used to store high definition video (HD) and high density storage. -
HD-DVD
High-Density Digital Versatile Disc (HD-DVD), a digital optical media format, uses the same disc size as Blu-Ray. -
WMV-HD
The Windows Media High Definition Video (WMV-HD) references high definition videos encoded with Microsoft Media Video nine codecs. WMV-D is compatible for computer systems running Windows Vista, Microsoft Windows XP. In addition, WMV-D is compatible with Xbox-360 and Sony's PlayStation 3. -
Holographic
Holographic memory can store digital data at high density inside crystals and photo-polymers. The advantage of holographic memory lies in its ability to store a volume of recording media, instead of just on the surface of discs. In addition, it enables a 3D aspect that allows a phenomenon known as Bragg volume to occur. -
Cloud Storage
Improvements in internet bandwidth and the falling cost of storage capacity means it’s frequently more economical for business and individuals to outsource their data storage to the cloud, rather than buying, maintaining and replacing their own hardware.
