An optical recording medium is provided with: a first substrate having
first pits on one face thereof; a first reflective layer that is formed
on the face bearing the first pits of the first substrate in a manner so
as to reflect lands and recesses of the first pits; a second substrate
that is formed on the first reflective layer, with second pits being
formed on a face on the side opposite to the first reflective layer; a
second reflective layer that is formed on the face bearing the second
pits of the second substrate in a manner so as to reflect lands and
recesses of the second pits; and a cover layer formed on the second
reflective layer. In this structure, the first pit depth d.sub.1 that is
a difference between lands and recesses of the first reflective layer,
the wavelength .lamda. of signal-reproducing laser light and the
refractive index n.sub.1 of the second substrate satisfy the following
relational expressions:
.lamda./(5n.sub.1).ltoreq.d.sub.1.ltoreq..lamda./(3n.sub.1) and
d.sub.1.noteq..lamda./(4n.sub.1). Moreover, the second pit depth d.sub.2,
which is a difference between lands and recesses of the second reflective
layer, the wavelength .lamda. of signal-reproducing laser light and the
refractive index n.sub.2 of the cover layer satisfy the following
relational expressions:
.lamda./(5n.sub.2).ltoreq.d.sub.2.ltoreq..lamda./(3n.sub.2) and
d.sub.2.noteq..lamda./(4n.sub.2).
