A Disk Drive with Multiple Tracks: Seek Time
Understand the concept of seek time in hard disk drives with multiple tracks by exploring the phases of moving the disk arm, including acceleration, coasting, deceleration, and settling. Learn how these steps affect data access times, along with rotational delay and data transfer, for a comprehensive view of HDD I/O performance.
We'll cover the following...
So far our disk just had a single track, which is not too realistic; modern disks of course have many millions. Let’s thus look at an ever-so-slightly more realistic disk surface, this one with three tracks. Look at the figure given below.
In the figure, the head is currently positioned over the innermost track, which contains sectors 24 through 35. The next track over contains the next set of sectors (12 through 23), and ...
