Making hard drives for laptops and portable computers imposes different sets of design criteria on the engineer. What are the special considerations that the designer of mobile hard disks has to contend with?
What will be an ideal response?
Drives in laptops are far smaller than drives in desktops. This puts a pressure on the designers of portable disks to use the greatest possible areal density. Because the drives have to run off battery power, the power required to spin the disk and move the arm assembly should be minimized. Moreover, laptops are portable and they may be moved during operation. Consequently, it is necessary to do everything possible to ensure that the effect of shock (knocks) is minimized.
