a) Find the answers to these questionsin the following text.
1) What is Currie Munce’s main aim?
2) How quickly did the possible areal density of hard disks increase in the 1990s?
3) How long does Munce think magneticrecording technology will continue to make rapid advances in capacity?
4) What problem does he predict for magnetic storage?
5) What is the predicted limit for discrete bit magnetic storage capacity?6) What storage technologies might replace current magnetic systems?
7) What is the advantage of holographic storage being three-dimension?
8) What improvements are predicted due to thefast access rates and transfer times of holographic storage?
9) What is predicted to be the most important high capacity removable storage media in the next 10 years?
10) What method ofsoftware distribution is likely to replace optical disks?
b) Re-read the text to find the answers to these questions.
1. Match the terms in Table A with the statements in Table B.
Table A:
a.Big Blue
b. Areal density
c. Moore’s Law
d. Superparamagnetism
e. Terabit
f. AFM
g. Angstrom

Table B:
I. Atomic force microscopy
II. The approximate radius of anatom
III. IBM
IV. The data capacity of a storage device measured in bits per square inch
V. Prediction that the number of transistors that can be incorporated into a processor chip willdouble every 18 months
VI. A phenomenon that threatens to mmake densely packed bits unstable in magnetic storage devices
VII. One thousand gigabits

2. Mark the following statements as Trueor False:
a) The development of AFM is more advanced than holographic storage. FALSE
b) The predicted maximum storage density of AFM is 400 gigabits per square inch. TRUE
c) Holography...
