Q10.1 Magnetic tapes provide sequential access so it has to start and stop and reverse the head direction to search for the data. While the disk is rotating continuously and it can provide random access of data so the read write operation is easier in disks than the magnetic tape. Read/Write operation in hard disk most hard disk consist of several coaxial platters, these platters continuously move around the axis. the collection of number of platters forms a cylinder the read/write head is over the
