Magnetic recording medium |
| abstract |
A magnetic recording medium having on a support at least two magnetic layers that include an uppermost magnetic layer for recording information and a lower magnetic layer for recording servo signals, wherein the uppermost magnetic layer has a coercive force Hc(U) [KA/m] at most 265 times as much as a saturated magnetic flux density Bs[T] of a recording head used for information recording and the lower magnetic layer has a coercive force Hc(L) [KA/m] at least 159 times as much as the saturated magnetic flux density Bs[T] of the recording head used for information recording, thereby ensuring highly accurate servo write and elevation of recording density. |
