AB  - When using spiral-groove frequency test records as the signal source for the determination of disc-reproducer performance, it is recognized that a gradual decrease in reproduced level occurs from the outside to the inside of the disc. Along with this, there occur instantaneous variations which tend to reduce the accuracy of measurements. It was felt that these difficulties could be minimized by the use of locked concentric grooves. The relative merits of both types of grooves are discussed, and experimental data presented.
