The
answer is FALSE because the
interior of commercial Hard disk drive is with stack of magnetic disks
(platters) containing the user’s data and a rotating arm supporting the magnetic
heads. The rotating arm is moved by the torque generated by a voice coil motor
(VCM) mounted at one end of the arm. Data read/write operations rely on the capability of the
governing unit of the HDD to maintain the magnetic read/write heads as close as
possible to center of the desired track. Typically, reliability of data reading
and writing is guaranteed when the head is kept within 5% of the track pitch
from the track center. This means that the accuracy required for the head positioning
is in the range of a few tens of nanometers.
