Full Title
Full titles differ between systems:
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 > Supporting in balanced, counterbalanced, or loaded operative position, e.g. loading in direction of traverse > by elastic means, e.g. spring
