An information recording medium capable of avoiding insertion of a sheet material into a drive unit. The information recording medium is comprised of a tape cartridge that rotatably accommodates a tape reel wound with a tape-shaped recording medium (magnetic tape), a storage case that accommodates the tape cartridge, and a sheet material that is accommodated in the storage case together with the tape cartridge. The sheet material is formed to have a size in an unfolded state small enough to be accommodated in the storage case, and is accommodated in the storage case in a state where the sheet material is folded along a folding line.
