What are the major obstacles faced by the designer of hard drives?
What will be an ideal response?
Designing hard drives is not a trivial matter because of all the factors involved. A disk drive is a complex electrical, electronic, and mechanical system operating at the very edge of the state?of?the art. A major task is to position the read/write head quickly and repeatedly above a very small track. This requires precision engineering (and complex control systems to keep the head in place). Another problem concerns the design of the disk surface. It is necessary to create the smallest possible regions of stable magnetization. This requires a knowledge of advanced materials science.
