| alternating velocity which would be imparted to a stylus tip of negligible dimensions, fitted to a pick-up head having no mechanical impedance when tracing the groove of a record rotating with a constant angular velocity
NOTE 1 – The recorded velocity is represented by a vector with a lateral and a vertical component for records with stereophonic recording.
NOTE 2 – The recorded velocity may be measured by the Buchmann and Meyer method. It should always be stated whether r.m.s. or peak values are implied.
