A magnetic recording medium improved in spacing loss and durability is disclosed. The magnetic recording medium is composed so that a magnetic layer is formed on a non-magnetic support, further thereon a non-magnetic protective layer having projected portions formed thereon in a discrete manner according to a thickness distribution, and further thereon a lubricant layer is formed so as to produce surface projections. In other words, the projected portions are formed in a discrete manner to the non-magnetic protective layer formed on the magnetic layer, where the non-magnetic protective layer is principally intended for the purpose of rust prevention or the like for the magnetic layer. The whole portion of the non-magnetic protective layer inclusive of the projected portions is composed with the same material.
