In situ NFT pre-treatment to accumulate optically transparent material on NFT to improve reliability

The disclosure relates to pre-processing a magnetic recording head to extend the lifetime of a magnetic media driver. Transparent smears are purposefully formed on the magnetic recording head to ensure that the magnetic recording head does not overheat and lead to short driver life. The transparent smear is formed from a material present in a magnetic medium. The transparent smear is formed by pre-processing the magnetic recording head using a transparent material from the magnetic medium. The pre-processing is performed without writing any data to the magnetic medium. Once the transparent smear is in place, writing can be performed. If the transparent smear is degraded, the magnetic recording head may be reprocessed at a later time. In addition, if an optically absorbing smear is produced, it may be removed and a new transparent smear may be formed. 本公开涉及预处理磁记录头以延长磁介质驱动器的寿命。将透明涂抹物有目的地形成于所述磁记录头上以确保所述磁记录头不会过热且导致短驱动器寿命。所述透明涂抹物由磁介质中存在的材料形成。所述透明涂抹物是通过使用来自所述磁介质的透明材料预处理所述磁记录头而形成。所述预处理在不将任何数据写入到所述磁介质的情况下进行。一旦所述透明涂抹物
