False.
No, they don't. There is only microns between them but they don't actually touch.
Think about it, the plates are spinning at a minimum of 3600 rpm and thousands of read/write actions a minute. How long would it last if it actually touched? When a head touches a plate it's called a "head crash" and results in damage to the head, plate or both.

False. The heads are very close to the disk,but do not need to touch it,as data is written to and read from the disk by means of magnetic induction. When the head accidently touches the magnetic material on the disk,severe damage usually results. (this sometimes happens if the hard disk drive suffers a heavy impact)

No. The heads float above the disk. Remember that the disk is spinning at perhaps 7200 revs per minute. Anything that touches it would scratch the surface creating 'bad sectors'. The manufacturers go to great lengths to ensure the heads don't touch and build in shock absorbtion into the drive. The data is read by the head magnetically not by physical contact. Obviously we learn that a bogus technical qual is not worth the paper its written on. (I know this for sure as I have many tech certs including MSCE, Novell, Oracle etc)
You can verify this by a quick google or visit a vendor website.

False, hard disk is working by magnetism, if the surface is sanded away b/c of touching, damage will result.

True. Otherwise how else would it read the disk?
