<p>The attachment is used in devices with disc data carriers for computers - floppy disc devices, hard discs (magnetic, magnetic-optic and others). It reduces many times the access time to the information recorded on these carriers, and, depending on the speed of the disc revolution it is in the range of 100 to 200 ms. In addition more than one such a set with heads can be mounted on the supporting busbars. Such attachments are suitable for multiprocessor computer systems, as each processor can read and recorded information regardless of the remaining ones. The attachment also contains one or more supporting busbars (2) which completely intersect the information surfaces of the disc. As many heads (1) can be fitted as is the number of paths (4) has the carrier, i. e. above each information path (4) there is a head (1). The selection of the required heads (1) for information recording or reading is made by electronic switching (5) and the time of this switching is in the order of nanoseconds. 2 claims, 2 figures</p> |
