Magnetic tape recording and reproducing apparatus for digital signals of still pictures in the pal system

A magnetic tape recording and reproducing apparatus for converting received PAL system video signals of still picture data into digital signals, and recording and reproducing on a magnetic tape, comprising:

• a memory possessing a capacity for storing a portion of one field of the PAL system video signals in which two fields compose one screen,
• means for recording by storing the PAL system video signals for said one field in the memory as the still picture data, and recording the stored still picture data onto the magnetic tape while sequentially reading out from the memory, and
• means for reproducing by reading out the still picture data for said one field from the magnetic tape and storing said one field in the memory, and means for repetitively reading out from said memory the still picture data of said one field, and the still picture data for one false field of said one field which excludes the data of a specific scanning line section of said one field out of the still picture data, and said means for repetitively reading out producing still picture data in which the number of scanning lines of a scanning line period that are in phase and occur across a vertical synchronizing signal is an even number.
