Question
Explain landing zones and their technologies?
Answers
When a hard disk is functioning normally the read write head simply fly`s over the platter without making any contact.
These days to prevent the head from touching the platter the head are physically moved ( parked) to special areas also known as landing zones to prevent data loss.
The landing zones are usually areas where no data is stored.
Another approach is to leave the heads suspended in air so that they never come in contact with the platter surface.
In legacy devices the heads could not be automatically landed and in order to prevent them from touching the platter the user had to run programs manually to park the heads.   Your Comment
