Or flux changes per inch perhaps?
It appears you have it. From Seagate
http://www.seagate.com/support/glossary/terms/fcpi.html
"Flux changes-per-inch. The linear recording density defined
as the number of flux changes-per-inch of data track.
Synonymous with flux reversals-per-inch (FRPI). In MFM
recording 1 FCPI equals 1 bit per inch (BPI). In RLL encoding
schemes, 1 FCI generally equals 1.5 BPI. "
