It places the drive head in a position that is least likely to cause damage to the drive if it is removed or moved physically.
no, the head not touching the surface of the hard disk. If it touch the great chance of data may be lost. only the head of floppy disk is touch the surface of the disk.
HDI - Head to Disk Interference.
A head crash is a type of hard disk failure that occurs when a read/write head touches the fast spinning disk platters. It is very catastrophic - it can destroy lots of data - even the data needed to start an operating system can be destroyed.

Ferrite or cobaltite crystals are within a hard disk.
hard drive head crash
The head(s) in floppy drives make physical contact with the floppy disk surface, while the heads in hard disk drives fly over the hard disk surface on a cushion of air created by the platter rotation speed. All other features of the devices are similar.
Magnetic HARD Disk Drive constitutes of a Disk Platter, Spindle Motor, Read Write Head, Logic Card and Metal Casing with connector.
A computer hard disk or hard drive (fixed disk) is hardware.
Hard-disks are coated with iron oxide because it reacts to a magnetic source ! The information on a hard-disk is read and written by a magnetic 'head' which scans across the surface as the disk rotates.
Head – The device that reads and writes the information—magnetic or optical—on the disk surface.
