Drum memory was a magnetic data storage device invented by Gustav Tauschek in 1932 in Austria. [1] [2] Drums were widely used in the 1950s and into the 1960s as computer memory. Many early computers, called drum computers or drum machines, used drum memory as the main working memory of the computer. [3]
At the time of their introduction the storage capacity exceeded any other random access mass storage disk or drum. There were three models of FASTRAND drives: FASTRAND I had a single drum. The large mass of the rotating drum caused gyroscopic precession of the unit, making it tend to spin on the computer room floor as the Earth rotated under it ...
The Linn 9000 was Roger Linn's first attempt to create an integrated sampling/sequencing/MIDI workstation, but it was plagued with problems from the beginning. [5] [6] On early models, the power supply over-heated the CPU and had to be replaced under warranty, but insurmountable issues with the Linn 9000's operating system forced its eventual demise.
The LinnDrum Midistudio (also known as the Midistudio) was going to be an electronic musical instrument produced by Linn Electronics as the successor to the ill-fated Linn 9000, which was an integrated digital sampling drum machine and MIDI sequencer. The Midistudio is essentially a rack-mount version of the Linn 9000 with some improvements. [1]
The IBM 2301 is a magnetic drum storage device introduced in the late 1960s to "provide large capacity, direct access storage for IBM System/360 Models 65, 67, 75, or 85." The vertically mounted drum rotates at around 3,500 revolutions per minute, and has a head-per-track access mechanism and a capacity of 4 MB.
This later device shares the control array and display of the DR-220, with the addition of a MIDI In port. The MkII version had access to 91 16-bit drum sounds, allowing the user to control parameters of each sample such as decay length and filtering. It had 64 preset patterns and room for 64 user-created patterns.
The IBM 650 Magnetic Drum Data-Processing Machine is an early digital computer produced by IBM in the mid-1950s. [ 2 ] [ 3 ] It was the first mass-produced computer in the world. [ 4 ] [ 5 ] Almost 2,000 systems were produced, the last in 1962, [ 6 ] [ 7 ] and it was the first computer to make a meaningful profit. [ 7 ]
The phonograph may be considered a storage device especially as machines of this vintage were able to record on blank cylinders. On a reel-to-reel tape recorder (Sony TC-630), the recorder is data storage equipment and the magnetic tape is a data storage medium. Various electronic storage devices, with a coin for scale.
