An optical recording medium comprises a transparent lower disk and an upper disk secured together by a transparent intermediate member. On one side of the lower disk, groove tracks of width W.sub.G0 and land tracks of width W.sub.L0 are formed. All tracks of the lower disk are coated with a recording film on which a laser beam is incident from below and a reflecting film on the recording film for partially reflecting the laser beam. The upper disk is formed with land tracks of width W.sub.L1 and groove tracks of width W.sub.G1 for receiving light through the corresponding groove and land tracks of the lower disk. All tracks of the upper disk are also coated with laminated recording and reflecting films. The ratio W.sub.G1/W.sub.L1 of the upper disk is greater than unity and is equal to or greater than the ratio W.sub.G0/W.sub.L0 of the lower disk so that the carrier-to-noise ratios of the two disks are substantially equal to each other.
