(a) Let us assume a disk with rotational speed of 15,000 rpm, 512 bytes per sector, 400 sectors per track and 1000 tracks on the disk, average seek time is 4ms. We want to transmit a file of size I MByte, which is stored contiguously on the disk. Determine the following: (i) What is the transfer time for this file? (ii) What is the average access time for this file? ) What is the rotational delay in this case? bt A magnetic disk with 5 platters has 2048 tracks/platter, 1024 sectors/track (fixed number of sectors per track), and 512-byte sectors.
