Your computer has one or more of the following types of drives:

360KB drive-Uses 

 double-sided, doubledensity, 360KB disk-

ettes. (You can also use single-sided, 160KB or 180KB diskettes.) These

diskettes contain 40 tracks per side, 8 or 9 sectors per track, and hold up

to 360KB of information. (With 8 sectors per track, a diskette holds

320KB.) KB stands for kilobyte; each kilobyte equals 1024 bytes.

1.2MB drive-Uses 

 double-sided, high-density, 1.2MB disk-

ettes. These diskettes contain 80 tracks per side, 15 sectors per track, and
hold up to 1.2MB of information. MB stands for megabyte; each mega-

byte equals 1,048,576 bytes.

720KB drive-Uses 

 double-sided, double-density, 720KB disk-

ettes. These diskettes contain 80 tracks per side, 9 sectors per track, and
hold up to 720KB of information.

1.44MB drive-Uses 3 

 double-sided, high-density, 1.44MB disk-

ettes. These diskettes contain 80 tracks per side, 18 sectors per track, and

hold up to 1.44MB of information.

If your computer has more than one of these drive types, you need to be

aware of certain incompatibilities between the drives and the diskettes they

use. These incompatibilities also apply to the same type of diskette drives on
other compatible computers.

Because of the difference in size, you cannot use 

 diskettes in a

 drive or vice versa. Additionally, there are certain limitations on

using diskettes that are the same size as the drive but have different capaci-

ties. Tables 3-1 and 3-2 summarize the possibilities and limitations.
