1.   The computer-controlled telescope stores these images on magnetic media.

2.   In general, all restores would then be carried out from the optical disk, minimising the number of mounts needed for the magnetic media.

3.   In the case of magnetic media the signal degrades, and the access mechanisms become obsolete as new standards of storage and access evolve.

4.   Magnetic media, the most common means of information storage for machine-readable software and data, are notoriously impermanent.

5.   Both Bradley and Gore have enlisted the aid of consultants and coaches over the years in hopes of becoming more magnetic media personalities.

6.   Data on magnetic media like disks and tape grows fainter with age, to the point where it may eventually be irretrievable.

7.   Fully optical technology like CDs promise much better longevity than magnetic media like tape and disks for storing very large memory-intensive files.

8.   Magnetic media like hard discs, Zip discs or backup tapes are less reliable but viable options.

9.   NARROW TRACKS CUT DATA COSTS An improved production process makes it possible to construct silicon recording heads that lay down three times as much data on magnetic media.

10.   The Jaz cartridge itself is a hybrid design that uses two platters of a special magnetic media stored in a hard-plastic container.
