ANSI/ISO track locations. See the simple diagram
below for the three standard ANSI/ISO tracks.
Each track can be encoded and decoded with ASCII
characters in the standard default ANSI/ISO data
formats.

The ANSI/ISO data formats include a preamble (all
zeros), a start character, data (7-bit or 5-bit as
specified by ANSI/ISO), a stop character, and a
longitudinal redundancy check character. The 7-bit
data format has 6 bits of encoded data and a parity
bit. The 5-bit data format has 4 bits of encoded data
and a parity bit.
The ANSI/ISO data formats include a “data field”
separator (or delimiter) that allows the encoded
data on a track to be parsed. An example of sepa
