HD (Hard Drive) Question:
Explain Landing zones and their technologies?
Answer:
★ 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.
