360KB drive-Use doubleaided, double-density,
48 TPI, 360KB diskettes. (Y OU can also use single-sided,
160KB or 180KB diskettes.) These diskettes contain 40
tracks per side and 8 or 9 sectors per track. With 8 sectors
per track, a diskette holds up to 320KB. With 9 sectors per
track, a diskette holds up to 360KB of information, which is
approximately 150 pages of text.

135 TPI, 720KB diskettes. These diskettes contain 80 tracks

You must format a new diskette before you can store data on
it. See “Formatting Diskettes,” later in this section.
Drive and diskette incompatibilities
If your computer has more than one type of diskette drive, or if
you use different types of diskettes, you need to be aware of
certain incompatibilities between the drives and diskettes.
Because of the type and size differences, you cannot use a
diskette in a drive or vice versa. There are
also limitations on using diskettes that are the same size as the
drive but have different capacities. The following tables
summarize the possibilities and limitations.
