by sensing auxiliary features on record carriers or containers, e.g. to stop machine near the end of a tape

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Driving, starting or stopping record carriers of filamentary or web form; Driving both such record carriers and heads; Guiding such record carriers or containers therefor; Control thereof; Control of operating function > Control of operating function, e.g. switching from recording to reproducing > by sensing features present on, or derived from, record carrier or container > by sensing auxiliary features on record carriers or containers, e.g. to stop machine near the end of a tape

CPC:

Driving, starting or stopping record carriers of filamentary or web form; Driving both such record carriers and heads; Guiding such record carriers or containers therefor; Control thereof; Control of operating function (driving or guiding heads G11B3/00 - G11B7/00, G11B21/00) > Control of operating function, e.g. switching from recording to reproducing > by sensing features present on or derived from record carrier or container (G11B15/16 takes precedence) > by sensing auxiliary features on record carriers or containers, e.g. to stop machine near the end of a tape

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
