magnetic tape drives造句

• All these systems were less reliable and slower than purpose-built magnetic tape drives.
• A magnetic tape drive was added in 1952 but never worked sufficiently well to be of real use.
• Channel A and B were used to control magnetic tape drives, and Channel D controlled the 1301 disk.
• Despite this, innovation in the technology continues, and Sony and IBM continue to produce new magnetic tape drives.
• Most systems include at least two magnetic tape drives, operating at up to 75 inches / second at 800 bpi.
• The devices used a special " incremental " magnetic tape drive that was controlled by the STR communications unit.
• This division made punched card readers and 9-track magnetic tape drives for both parent companies ( CDC and NCR ).
• The SS II series included two enhancements-- the addition of 1, 280 words of core memory and support for magnetic tape drives.
• The assemblies can locate and transmit data seconds faster than other formats, such as the magnetic tape drives that were previously used to store computer data.
• The smaller, more elegant, single silo design incorporated two redundant CDC 1604 computer systems, each equipped with dual cabinets containing four 200 bpi magnetic tape drives.
• The IBM Endicott History and Heritage Center in Endicott, NY has a non-working System / 360 Model 30 and an associated 2401 magnetic tape drive on display.
• Large backups are often instead made on external hard drives, as their price has dropped to a level making this viable; in professional environments magnetic tape drives are also used.
• While the H200 supported operation with just a console, card reader and punch like the IBM 1401, the generic Input-Output instructions also supported line printers and magnetic tape drives.
• These motors were originally invented to drive the capstan ( s ) of magnetic tape drives in the burgeoning computer industry, where minimal time to reach operating speed and minimal stopping distance were critical.
• In a completed and working magnetic tape drive system, the tape-drive heads apply a very specific magnetic field to the tape; the tape then induces a change in electric current, which is captured.
• The H1800-II consisted of an H1800 mainframe equipped only with magnetic tape drives and an online adaptor ( OLA ) connection to a satellite H200 to simulate a card reader for reading low volumes of job control cards.
• The LINCtape magnetic tape drive, designed by Wesley A . Clark for the LINC, was suitable for handling in a laboratory environment, and the tapes could be carelessly pocketed, dropped, or even pierced and cut without losing the data stored on them.
• The 7080 system included the IBM 7622 Signal Control, which converted transistor signal levels to levels usable with first generation equipment, allowing all 705 peripherals, including punched card input / output, line printers and the IBM 727 magnetic tape drives, to be used on the 7080.
• Run queues evolved from a literal queue of people at the door, to a heap of media on a jobs-waiting table, or batches of punch-cards stacked one on top of the other in the reader, until the machine itself was able to select and sequence which magnetic tape drives processed which tapes.
• A " typical " configuration might consist of a S / 360 model 30 with 32KB memory and the decimal instruction set, an IBM 2540 card reader / card punch, an IBM 1403 printer, two or three IBM 2311 disks, two IBM 2415 magnetic tape drives, and the 1052-7 console.
