Abstract
The first part of the paper outlines briefly the advantages of disk as compared with other systems of recording. Groove spacing, groove velocity, and direction of cut as applied to 16-inch disks are discussed, and a conclusion is reached regarding the best compromise which can be used. Recording characteristics are considered in detail and a characteristic is recommended which could be used generally. The use of automatic equalizers to improve the frequency response at low groove velocities is also recommended. The more essential requirements of recording heads and gramophone pickups suitable for the cutting and playing of cellulose nitrate disks are discussed.
