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 ...
Later, optical disc drives and flash memory units are also classified as DASD. [2] [3] The term DASD contrasts with sequential access storage device such as a magnetic tape drive, and unit record equipment such as a punched card device. A record on a DASD can be accessed without having to read through intervening records from the current ...
The Roland DDR-30 Digital Drum module is designed to pair with PD-10 and PD-20 pads to form the Alpha Drum System, or via MIDI controller (e.g. Roland Pad 8). [3] The DDR-30 and Alpha Drums was the first-generation of Roland electronic drum sets.
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.
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.
A Maxell-branded 3-inch Compact Floppy Disk. The floppy disk is a data storage and transfer medium that was ubiquitous from the mid-1970s well into the 2000s. [1] Besides the 3½-inch and 5¼-inch formats used in IBM PC compatible systems, or the 8-inch format that preceded them, many proprietary floppy disk formats were developed, either using a different disk design or special layout and ...
The Yamaha RX-5 is a programmable digital sample-based drum machine built by Yamaha, in 1986. [3]With the extensibility of sample-sounds via Waveform Data Cartridge, [4] and the multiple voice-parameters [5] (including chromatic pitch and envelope [6] [4]) controlled for each note, [7] Yamaha RX5 offered the ability to create relatively simple sample-based music tracks all in one device, as on ...
