Consider a disk with a sector size of 512 bytes, 2000 tracks per surface, 50 sectors per track, five double-sided platters, and average seek time of 10 msec. Suppose that a block size of 1024 bytes is chosen. Suppose that a file containing 100, 000 records of 100 bytes each is to be stored on such a disk and that no record is allowed to span two blocks.

a). If the file is arranged sequentially on the disk, how many surfaces are needed?

b) How many records of 100 bytes each can be stored using this disk?

c)If pages are stored sequentially on disk, with page 1 on block 1 of track 1, what page is stored on block 1 of track 1 on the next disk surface?
