Question

Time required to move a current track i​

Answer 1

Answer:

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.

please thank my all answer and mark as brianliest

Answer 2

Answer:

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.
