4. Given the following characteristics for a disk pack with 10 platters yielding 18 recordable surfaces: Rotational speed =10ms Transfer rate =0.1ms/ track Density per track =19,000 bytes Number of records to be stored =200,000 records Size of each record =160 bytes Block size =10 logical records Number of tracks per surface =500 Find the following: a. Number of blocks per track b. Waste per track c. Number of tracks required to store the entire file d. Total waste to store the entire file e. Time to write all of the blocks (Use rotational speed; ignore the time it takes to move to the next track.) f. Time to write all of the records if they're not blocked. (Use rotational speed; ignore the time it takes to move to the next track.) g. Optimal blocking factor to minimize waste h. What would be the answer to (e) if the time it takes to move to the next track were 5ms ? i. What would be the answer to (f) if the time it takes to move to the next track were 5ms
