2. Consider a disk with a sector size of 1024 bytes, 1,000 tracko per surface, 100 sectors per track, 7 single-sided platters and a block alze of 2,048 bytes. Suppose that a file containing 1,000,000 records of 90 bytes each is to be stored on such a disk and that no record is allowed to span two blocks. [3 Marks] How many records fit onto a track? How many blocks are required to store the tire file? If the file is arranged sequentially (contiguouslycording to the 'next block concept') on disk, how many linders are needed
