There is disclosed a transparent magnetic recording medium having, on a support, at least one magnetic recording layer containing magnetic particles, which medium comprises a first set of protuberances having a height of 0.001 mum or more than 0.001 mum, but less than 0.1 mum, and a density of from 1x102 pieces/100 mum2 to 1x105 pieces/100 mum2, and a second set of protuberances having a height of from 0.1 mum to 0.5 mum, and a density of from 1 piece/100 mum2 to 200 pieces/100 mum2, on a surface that is at the side of said at least one magnetic recording layer provided, wherein the difference of height between the first set of protuberances and the second set of protuberances is 0.1 mum or more but 1.0 mum or less; and said medium contains at least first and second kinds of inorganic particles and/or organic high-molecular particles, each of which has different average primary particle diameters, in at least the magnetic recording layer or an outer layer positioned such that the magnetic recording layer lies between said outer layer and said support, the average primary particle diameter of the first kind of the inorganic particles and/or organic high-molecular particles used to obtain the second set of protuberances being more than 0.4 mum, but 1.5 mum or less. This transparent magnetic recording medium is assuredly capable of recording/reproducing various magnetic information, with little occurrence of magnetic error.
