packing density

[′pak·iŋ ‚den·səd·ē]
(computer science)
The amount of information per unit of storage medium, as characters per inch on tape, bits per inch or drum, or bits per square inch in photographic storage.
(electronics)
The number of devices or gates per unit area of an integrated circuit.
(geology)
A measure of the extent to which the grains of a sedimentary rock occupy the gross volume of the rock in contrast to the spaces between the grains; equal to the cumulative grain-intercept length along a traverse in a thin section.

packing density

The number of bits or tracks per inch of recording surface. Also refers to the number of memory bits or other electronic components on a chip.
