Present-Day Developments in Magnetic Pickups
The electrical signal generated by the pickup is compared with the mechanical motion of the cutting stylus. The inherent relationship between the two is discussed. It is shown that the magnetic pickup does not, of itself, require equalization, but rather, that compensation is needed in the playback circuit to secure a resposne characteristic which is the conjugate of the equalization inserted in the recording channel ahead of the magnetic cutter. In the second part of this paper, the author attempts to correlate lateral mechanical impedance with the overall tracking capabilities and performance of the modern high-quality pickup.
