bit density

[′bit ′den·səd·ē]
(computer science)
Number of bits which can be placed, per unit length, area, or volume, on a storage medium; for example, bits per inch of magnetic tape. Also known as record density.

bit density

The number of bits that can be stored within a given physical area. See bpi.


A Memory Bit
This is one storage cell in an earlier 16-megabit DRAM memory chip. Although minuscule in overall capacity compared to today's memory, there were 16,777,216 of these cells in the chip, which was only a quarter of an inch square. (Image courtesy of IBM.)
