  • Patent number: 11562766
    Abstract: A thermally assisted magnetic head includes a slider, the slider includes a slider substrate and a magnetic head part. The magnetic head part includes a recording head, a reading head, a near field transducer and a medium-opposing surface. The medium-opposing surface includes a recording area and a reading area. The magnetic head part includes a record/read separately protective structure which an enhanced protective film is formed on the recording area and a reading head protective film is formed on the reading area. The enhanced protective film includes a plurality of films for effectively protecting the recording head and the near field transducer. The reading head protective film includes a thickness which is thinner than the enhanced protective film.

  • Patent number: 9840767
    Abstract: A manufacturing method for a head slider coated with Diamond-like Carbon (DLC) includes: providing a substrate that is to be finally made into a head slider; depositing a DLC layer on a surface of the substrate, with carbon plasma source being sputtered in a direction that is vertical to the surface of the substrate; and doping a fluorine-doping (F-doping) layer on the DLC layer. Whereby the head slider has good film adhesion performance, higher hardness, better wear resistance, lower surface energy to obtain good hydrophobicity and oleophobicity, and lower fly height in HDD.
