The present invention provides a magnetic recording medium, particularly a linear recording tape for a computer, which has a back coat layer having appropriate strength, is excellent in electromagnetic conversion characteristics, and is also excellent in running durability characteristics. A non-magnetic support has a lower non-magnetic layer on one surface, an upper magnetic layer on the lower non-magnetic layer, and a back coat layer on the other surface of the non-magnetic support. a magnetic recording medium having, in the magnetic layer sendust wear volume amount S MC is at 3.0 × 10 4 (μm) 3 / m or less, and the back coat layer of sendust wear volume amount S BC and the magnetic layer the ratio of sendust wear volume amount S MC (S BC / S MC ) is a magnetic recording medium is 0.5 to 3.0.
