摘要 |
<p>A magnetic recording medium has a magnetic recording medium sheet (2) formed of a sheet-like magnetic recording medium material having at least a magnetic recording layer, and a pair of nonwoven fabric layers (5a, 5b) arranged so as to sandwich the magnetic recording medium sheet (2) therebetween and to face the two surfaces thereof for protecting the magnetic recording medium sheet (2). The nonwoven fabric (5a or 5b) facing at least one surface of the magnetic recording medium sheet is impregnated with a lubricating oil solution, diluted with a solvent, in advance such that the nonwoven fabric (5a or 5b) is provided on the magnetic recording medium sheet (2) after being subjected to both the lubricating oil solution impregnation step and a drying step.</p> |
