11. Magnetic storage includes hard drives ( HDD ), magnetic tape such as videotape and is different from flash memory.12. The smaller size and accelerating density of magnetic storage systems is one of the remarkable stories of Silicon Valley. 13. Since 1987, she has been studying magnetic storage at the information storage research center at Shanghai Jiao Tong University. 14. Sales of all magnetic storage cartridges in November fell more than 25 percent from the same time last year. 15. Zuse founded another company, " Zuse KG " in Z22, the first computer with a memory based on magnetic storage . 16. The film company found a willing partner in Iomega, the largest manufacturer of magnetic storage cartridges in the United States. 17. In magnetic storage , the magnetic flux or magnetization doesn't necessarily change at the boundaries of bit cells to indicate bit states. 18. Finally, because of the small size of the bubbles, the density was in theory much higher than existing magnetic storage devices. 19. Magnetic storage uses different patterns of magnetisation in a magnetisable material to store data and is a form of non-volatile memory.20. Many NIST data publications had been converted to magnetic storage media, which could be purchased from the NIST Standard Reference Data Program.
