載の斜め走査記録の直線性補生装置。[Claims for Utility Model Registration] (1) A signal generated in synchronization with the rotation of a cylinder in a magnetic recording and reproducing machine such as a digital audio tape player that records and reproduces data by diagonally scanning a magnetic tape with a rotating head. What is claimed is: 1. A linearity correction device for diagonal scanning recording, characterized in that the linearity correction device for diagonal scanning recording is configured to correct the linearity of a cylinder lead angle by superimposing the same on a capstan drive signal. (2) As a signal generated in synchronization with the rotation of the cylinder, a numerical value corresponding to the cylinder rotation angle using a memory and a D/A converter is read out from the memory and taken out through the D/A converter. A linearity correction device for diagonal scanning recording as claimed in claim 1 of the registered utility model.
