The time taken for the read/write head to move to the correct track on the magnetic disk is called ___________.
The time taken for the read/write head to move to the correct track on the magnetic disk is called ___________.
The correct option is E Seek time
The time taken for the read/write head to move to
the correct track on the magnetic disk is called Seek time.
Seek time is the time taken for a hard disk
controller to locate a specific piece of stored data. Other delays include
transfer time (data rate) and rotational delay (latency).
When anything is read or written to a disc drive,
the read/write head of the disc needs to move to the right position. The actual
physical positioning of the read/write head of the disc is called seeking. The
amount of time that it takes the read/write head of the disc to to move from on
part fo the disk to another is called the seek time. The seek time can differ
for a given disc due to the varying distance from the start point to where the
read/write head has been instructed to go. Because of these variables, seek
time is generally measured as an average seek time.
Seek time is also measured in two other ways -
track to track and full stroke. Track to track is the amount of time it takes
the read/write head to search or seek between adjacent tracks. It is usually
measured in milliseconds, which is typically 2 to 4 ms and as low as 1 ms. Full
stroke is the amount of time required to seek the whole disc. Full stroke is
also measured in milliseconds. A seek time below 10ms is generally considered
acceptable for a hard disk.
