Driving or guiding during transducing operation

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Recording by mechanical cutting, deforming or pressing, e.g. of grooves or pits; Reproducing by mechanical sensing; Record carriers therefor > Arrangements of heads > Arranging, supporting, or driving of heads or of transducers relatively to record carriers > Driving or guiding during transducing operation

CPC:

Recording by mechanical cutting, deforming or pressing, e.g. of grooves or pits; Reproducing by mechanical sensing; Record carriers therefor (G11B11/00, take precedence) > Arrangements of heads > Arranging, supporting, or driving of heads or of transducers relatively to record carriers > Driving or guiding during transducing operation

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