11. The decoder separately recorded each red, blue and green field onto an analog magnetic disk recorder. 12. So to fulfill the large storage requirements of computers, magnetic disks and optical disks are generally used. 13. The discussions include Digital's magnetic disk , digital linear tape drive, solid-state disk drive and thin-film heads businesses. 14. The system also provided processing capabilities for data stored on magnetic tapes and magnetic disk storage units. 15. Magnetic disk storage became available in 1966.16. Because it records optically, the stored information is safer than it would be on a magnetic disk . 17. Consider the special case where the cylindrical conducting disk is stationary but the cylindrical magnetic disk is rotating. 18. The D-37C computer memory consists of a rotating magnetic disk driven by a synchronous motor at 6000 rpm. 19. They used magnetic disks , called floppies. 20. In 2005 06, a major shift in technology of hard-disk drives and of magnetic disks / media began.
