Abstract
To record and reproduce appropriately video signals of PAL system as still picture in a magnetic tape recording and reproducing apparatus. As still picture data, video signals for one field or two fields of system recorded in a magnetic tape after once stored in memories at the time of recording are read out when reproducing and stored simultaneously once in the memories. When storing the still picture data for one field, the still picture data of one field, and the still picture data for one false field which excludes the data of specific scanning lines from the still picture data are repeatedly read out from the memories. When storing the still picture data for two fields, the still picture data for the two fields, and the still picture data for two false fields which excludes the data in specific scanning lines from the still picture data are repeatedly read out from the memories, so that the number of scanning lines in phase face to face in the still picture data may be an even number.
