Given the following characteristics for a magnetic tape using linear recording as described in this chapter:
Density = 1600 bpi
Speed = 1500 inches/second
Size = 2400 feet
Start/stop time = 4 ms
Number of records to be stored = 200,000 records
Size of each record = 160 bytes
Block size = 10 logical records
IBG = 0.5 inch
Find the following:
a. Number of blocks needed
b. Size of the block in bytes
c. Time required to read one block
d. Time required to write all of the blocks
e. Amount of tape used for data only, in inches
f. Total amount of tape used (data + IBGs), in inches
