Now, should a request be made to read File A Wx" your system can nove its read-write heads (those mechanisms which actually read and write the data to and from the drives) to the begimning of File "X", and smoothly nove across the drive, reading sector by sector until the file has been completely read. Should you wish to read File "Z", the heads would simply move to the beginming of File "Z" and begin the same process. Now let's S delete File "Y". ....this will result in a "disk map" that looks like this: XX *X *XXX. LLLLLLLLLLL ...
