​KembaraXtra-Computer Terms – bits per inch:
Bits per inch is a measurement used to describe the storage density of data on magnetic storage media such as disks or tapes. It indicates how many bits of information can be stored within a single inch of the storage surface.
In disk storage systems, this measurement is calculated based on the circumference of a track on the disk. Higher bits-per-inch values indicate that more data can be stored within the same physical space, increasing overall storage capacity.
