THE FIXED DISK
Instead of using interchangeable plastic diskettes, the fixed disk drive
uses two built-in aluminum disks. The disks are permanently sealed
in a dust-free compartment within the drive.
The information stored on fixed disks is recorded in tracks and sectors
similar to those on diskettes. However, the disks built into the fixed
disk drive provide a capacity for the storage of 10 million bytes
(characters) of information. (That is approximately equal to the amount
of information that can be stored on twenty-eight diskettes.)
