Abstract

PURPOSE:To improve the reliability of a picture information system by providing information recording tracks for picture information and index recording tracks for index information. CONSTITUTION:A magnetic tape 3 has 200 parallel recording tracks 7 in its running direction (a). Two center tracks (track number : 99 and 100) are index recording tracks 71 where characteristic index information on the contents of picture information is recorded, and the remaining 198 tracks (track number: 0- 90 and 101-199) are information recording tracks 72 for the picture information. Track numbers of tracks on which the picture information are recorded are added to the index recording tracks and when they are coincident with the track numbers of the picture information recording tracks, the picture information are recorded and reproduced.
