摘要：

Bit percolation degrades the performance of high-density perpendicular magnetic recording. The magnetic cluster size determines the limit of the recordable bit length. In order to examine the parameter, which influences the high-density recording characteristics, we have investigated the relationship between magnetic cluster size and the recording bit length at which bit percolation begins to occur in a CoPtCr-SiO2 perpendicular magnetic-recording medium to the range of 1500 kfci. Our experimental data indicate that the onset of bit percolation takes place at a recording bit length close to the magnetic cluster size of the medium.
