Influence of Technology on Magnetic Tape Storage Device Characteristics
There are available today many data storage devices that serve the diverse application requirements of the consumer, professional entertainment, and computer data processing industries. Storage technologies include semiconductors, several varieties of optical disk, optical tape, magnetic disk, and many varieties of magnetic tape. In some cases, devices are developed with specific characteristic...
متن کاملMagnetic Tape Storage
Initially, magnetic tape for data storage was wound on large (10.5 in/26.67 cm) reels. This defacto standard for large computer systems persisted through the late 1980s. Tape cartridges and cassettes were available as early as the mid 1970s and were frequently used with small computer systems. With the introduction of the IBM 3480 cartridge in 1984, large computer systems started to move away f...
متن کاملMagnetic tape recording electrocardiograph.
R ECORDING the electrocardiogram for prolonged intervals presents difficulties from the standpoint of economy and convenience. One 200 foot roll of paper for a direct writing instrument is used in 40 minutes of continuous recording at 25 mm. per second, and reviewing this long electrocardiographic record is a cumbersome procedure. A convenient method of recording electrocardiograms and fied ele...
متن کاملPART: A Run-Time Library for Tape-Resident Data
Over the last decade, processors have made enormous gains in speed. But increase in the speed of the secondary and tertiary storage devices could not cope with these gains. The result is that the secondary and tertiary storage access times dominate execution time of data intensive computations. Therefore, in scientific computations, efficient data access functionality for data stored in seconda...
