For Areal Density we have terms and definitions in 4 topics. The topics are Computer Technology, Hard Drive Recovery, RAID Drive Recovery and Technology.

Areal Density (Computer Technology)

This typically refers to the amount of data that can be stored on a 1 inch square of material. It's usually represented in billions of bits per square inch on a hard drive platter. Hard drives with higher areal densities can store more information in an equal space than those with lower areal densities.

Areal Density (Hard Drive Recovery)

The number of bits of data that can be recorded onto the surface of a disk or platter usually measured in square inches. The areal density is calculated by multiplying the bit density (BPI - Bits Per Inch) by the track density (TPI - Tracks Per Inch).

Areal Density (RAID Drive Recovery)

The number of bits of data that can be recorded onto the surface of a disk or platter usually measured in square inches. The areal density is calculated by multiplying the bit density (BPI - Bits Per Inch) by the track density (TPI - Tracks Per Inch).

Areal Density (Technology)

This typically refers to the amount of data that can be stored on a 1 inch square of material. It's usually represented in billions of bits per square inch on a hard drive platter. For example, the first Toshiba 30GB hard drives that fit into 2.5" form factors had an areal density of 26.7 billion bits. Hard drives with higher areal densities can store more information in an equal space than those with lower areal densities.
