by sensing features present on or derived from record carrier or container (G11B15/16 takes precedence)

Introduced: January 1985

Title

Titles differ between systems:

IPC: by sensing features present on, or derived from, record carrier or container

CPC: by sensing features present on or derived from record carrier or container (G11B15/16 takes precedence)

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

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)

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
