HAMR MEDIA FOR ASSISTING OPTICALLY TRANSPARENT BUILDING ON NFT TO IMPROVE

The invention relates to a magnetic recording medium for a magnetic medium driver. During operation, the absorption smear may be developed on the magnetic recording head. Absorbing the smear results in shortened driver lifetime. On the other hand, compared with the absorbing smear, the transparent smear does not have the harmful effect on the service life of the driver. By doping the medium with a dopant that may lead to the development of a clear smear, the formation of an absorbing smear can be reduced or even eliminated, which leads to a longer driver lifetime. The dopant may be disposed in the capping layer of the media or in the absorber protection layer. During operation, the dopant will migrate through the medium to a top surface of the medium. The dopant will be deposited on the magnetic head from the top surface of the media and form a clear smear. 本公开涉及用于磁介质驱动器的磁记录介质。在操作期间，吸收涂片可以在磁记录头上发展。吸收涂片导致缩短的驱动器使用寿命。另一方面，与吸收涂片相比，透明涂片对驱动器使用寿命不具有那么有害的影响。通过将介质与可能导致透明涂片发展的掺杂剂掺杂，可以减少或甚至消除吸收涂片的形成，这导致更长的驱动器使用寿命。掺杂剂可以设
