Why is the access time for a moving head disc drive greater than the access time for a fixed head disc drive?

The access time for a moving head disc drive is greater than that of a fixed head disc drive due to the physical movement required by the read/write head to reach the desired location on the disk. In a moving head drive, the head needs to physically move across the disk's surface to access different sectors, resulting in increased latency. In contrast, a fixed head drive has multiple heads dedicated to specific locations on the disk, allowing for quicker access times as the heads do not need to physically move.
