Consider a disk with sector size of 512 bytes, 1000 tracks per surface, 50 sectors per track, five (5) double-sided platters, and average seek time of 8 msec. Suppose that the disk platters rotate at 7400 rpm (revolutions per minute). Suppose also that a block (page) of 2048 bytes is chosen. Now, consider a file with 150,000 records of 100 bytes each that is to be stored on such a disk and that no record is allowed to span two blocks. Also, no block can span two tracks.

1. How many records fit onto a block?

2. How many blocks are required to store the entire file? If the file is arranged sequentially on the disk, how many cylinders are needed?

3. How many records of 100 bytes each can be stored using this disk?
