In the information record medium, management information (PGCI) including (i) reproduction procedure information prescribing a reproduction procedure of the video information and (ii) a plurality of first search prohibit informations (202, 202a) each indicating a prohibition of a search operation by the reproducing apparatus for respective one of second data groups (61:PGC) each of which comprises a plurality of the first data groups to be reproduced continuously by the reproducing apparatus in accordance with the reproduction procedure information, is collectively recorded at one portion of the record track for each of the second data groups.
