Adj. Bit
The Adj. Bit, or adjacent bit, is the distance between the “zero” bit flux transition and the
previous bit cell, shown in Figure 3-13 as Bin + 1. The ISO standard abbreviates the adjacent bit
as Bin + 1 and calls it Adjacent Bit Cell Spacing Variation.

Adj. Sub.
The Adj. Sub., or adjacent subinterval, is the distance between a subinterval transition and the
previous subinterval, shown in Figure 3-13 as Sin + 1. The ISO abbreviates the adjacent
subinterval as Sin + 1 and calls it Adjacent Subinterval Spacing Variation.
Start Sent.
Start Sent., or Start Sentinel, is the distance from the edge of the card to the first subinterval flux
transition (the first one bit) encountered for each track.
