titleOfInvention |
Magnetic recording medium in the form of a disc |
abstract |
A magnetic recording medium in the form of a disc comprising a polyethylene naphthalate support having provided thereon a magnetic layer comprising ferromagnetic metal fine powder or ferromagnetic hexagonal ferrite fine powder dispersed in a binder, wherein the central plane average surface roughness of the magnetic layer of the magnetic recording medium is 5 nm or less, the thickness variation rate of the disc is 3% or less, and the total thickness of the disc X mum and the outside diameter of the disc Y mm satisfy the relationship of 0.3<=Y/X≤0.8. |
