Landing Zone
Regardless of the life of
a hard drive, the heads cannot be 'flying'
forever. Anytime a drive is not powered, the heads
are in contact with the platter. It makes sense, when
the heads are resting on the platter, to ensure
that data isn't under it. This is where the term
landing zone comes from. Putting the heads there is known as
head parking. Typically, heads are parked in a
landing zone that is one step beyond the last area
of data storage. In recent years, parking the heads is
an automatic process that happens on power down. Appropriately
enough this is called auto-parking.
A head crash can occur from
more than contamination. Physical shock can cause
a crash. Something notebook makers must concern themselves with. So,
with a read/write head made, it has to go somewhere.
If it doesn't move, you basically have a magnetic head stuck in one
position, like a cassette deck. How it moves is the next topic.
