  • Patent number: 8338006
    Abstract: A method for planarizing a magnetic recording disk that has surface features of elevated lands and recessed grooves includes forming two coatings of cured perfluorinated polyether (PFPE) polymers over the surface features. The disk may have a protective carbon overcoat with a surface that replicates the topography of lands and grooves. A liquid functionalized-PFPE is applied over the disk surface and then cured to form a first coating with the functionalized end groups bonding to the carbon overcoat. A liquid non-functionalized-PFPE polymer is then applied over the functionalized-PFPE coating and cured to form a second coating. The combined coatings substantially planarize the disk surface so that there is minimal recession between the top of the coating over the lands and the top of the coating over the grooves.

  • Patent number: 7952830
    Abstract: This application discloses a hard disk drive and operates it based upon using a first and third harmonic amplitude generated from reading a repeated pattern of bits written to a track on a disk surface. Both amplitudes are used to create a first data set and the third harmonic amplitude is used as a single tone to create a second data set. A conversion factor between these two is determine, which may be used to convert the first data set under other conditions into a temperature insensitive table of the electrical stimulus of a vertical micro-actuator and the flying height change of the slider. The hard disk drive may be calibrated during manufacture and/or in the field.

  • Publication number: 20100034966
    Abstract: A method for planarizing media disk surfaces with a polymer solution is disclosed. A non-functionalized lubricant is used to coat the disk surfaces without dewetting issues. The polymer is applied via soaking in a diluted solution for several minutes. The interaction of the polymer with the disk surface leads to preferential adsorption of lubricant into the valleys of the topography on the disk surface.

  • Patent number: 7486457
    Abstract: A method and apparatus for predicting write failure resulting from flying height modulation and initiating re-writing of data upon occurrence of the predicted write failure is disclosed. According to the present invention, if the slider or transducer flying height modulates during the write process, such modulation is detected, and a rewrite of the same data is forced. A write reassign may be initiated when a thermal signal exceeding the predetermined threshold is detected during the rewrite and/or a read/verify may be initiated after the rewrite.

  • Publication number: 20080212235
    Abstract: A slider for magnetic data recording. The slider has an air bearing surface with a trailing edge pad that is configured with a series of recesses that damp slider oscillations during use. The series of recesses formed in the trailing pad of the slider reduce slider oscillations by creating localized pressure gradients within the generally high pressure area over the pad. The slider can be configured with a raised primary pad and a secondary raised pad formed on the primary raised pad. A series of recesses formed in the secondary pad prevent slider oscillations, which would otherwise be especially problematic in a slider having such a secondary raised pad and associated higher pressure area thereover.

  • Patent number: 7417209
    Abstract: A system and method for preventing crosstalk noise from being superimposed on a read signal due to noise from a heater line for a slider in a recording disk drive is disclosed. A heater line pair to the slider is not grounded but is in a floating state with respect to an actuator support structure. A heater driver allows a heater current to flow between a positive power supply voltage and a negative power supply voltage. The heater line pair is not grounded, so an impedance is high as viewed from a magnetic disk. Thus, it is possible to effectively suppress a noise transmitted from the magnetic disk and read signal quality is kept from deteriorating due to the crosstalk from the heater line.

  • Patent number: 7352530
    Abstract: An apparatus and method for reducing a suspension gram load to increase head to disk interface reliability for contact recording systems. The method provides a suspension for reaching over a disk. A slider having a read/write head element on a trailing edge (TE) portion is also provided, the slider coupled with the suspension. In addition, a gram load of the suspension is reduced to minimize the friction force during contact of the TE with the disk such that when the TE portion of the slider contacts the disk the bouncing motion of the TE with respect to the disk is reduced.

  • Patent number: 7336434
    Abstract: A method for predicting the failure of a data storage device having a slider heater is disclosed. For slider heaters exhibiting a decreasing resistance aging characteristic, a failure warning is produced when heater resistance suddenly increases 2 to 5%, or dR/dt changes sign from negative to positive. For slider heaters exhibiting an increasing resistance aging characteristic, a failure warning is produced when the heater resistance suddenly drops 2 to 5%, or dR/dt changes sign from positive to negative. Additionally, random changes in heater resistance exceeding nominal measurement error may also be utilized to produce a failure warning. This method provides advance warning of potential data read/write errors well before the open circuit failure of the slider heater occurs.
