Picture signal recorder

Abstract

Abstract PURPOSE:To improve picture quality by adding a burst signal the same in phase as the sampling phase of a picture signal and a length different according to a track position in the partial period of the picture signal, and recording the picture signal. CONSTITUTION:Identification/burst signals to synchronize with a sampling clock from an identification burst signal generator 121 different in phase according to the length of a track are added to adequate positions having no picture signal such as vertical blanking periods in picture signals from gamma correcting processing circuits 106 and 107 in adders 108 and 109. Next, the picture signals, to which the identification burst signals are added, are passed through still video recording process circuits 110 and 111 and address 112 and 113, added to a pilot signal from a pilot signal generator 120, and recorded in a video floppy 118. Thus, the accurate phase matching between the picture signals and the sampling clock can be executed, and high picture quality can be obtained.
