摘要： Embodiments of the invention reduce a possibility that a head will collide with a medium when the clearance between the head and the medium is adjusted by using a medium, and sufficiently reduce the clearance even at an initial stage of accessing a data area. In one embodiment, a hard disk drive (HDD) keeps a heater in an OFF state for a period of time from the start of seek operation until the specified timing after a following mode starts. This prevents a head element from colliding with a magnetic disk, and also prevents flying properties from changing due to the deformation of the ABS. In the above specified timing, the heater is switched from OFF to ON. Specifically, for example, on completion of seek operation, in the timing in which a head arrives at a target track, or in the timing in which an HDC/MPU enters the following mode, the heater is turned ON.
摘要翻译：本发明的实施例减少了当通过使用介质来调整头部和介质之间的间隙时头部将与介质碰撞的可能性，并且即使在访问数据区域的初始阶段也足够地减小间隙。在一个实施例中，硬盘驱动器（HDD）将加热器保持在关闭状态，持续一段时间，从搜索操作开始直到在后续模式开始之后的指定定时。这样可防止头元件与磁盘碰撞，并且还防止由于ABS的变形引起的飞行性能的变化。在上述指定的时间，加热器从OFF切换到ON。具体地，例如，在寻道操作完成时，在头到达目标轨道的时刻，或者在HDC / MPU进入后续模式的定时中，加热器被接通。

摘要： A disk drive has a resistive heater located near the read/write head as a thermal fly-height actuator and uses an improved method for operating the fly-height actuator. As part of the method, the heater may be deactivated during a seek to minimize the risk of head-disk contacts. When a write command is received, a level of heater power is applied to pre-heat the write head prior to writing the initial data sectors. This pre-heating heater power level may be higher than the power level used for writing. Then when writing commences, the lower power level is applied to the heater so the write head has the optimal head-disk spacing during the writing of all the data sectors, including the initial data sectors. Even though the heater may be deactivated during the seek the controller can initiate pre-heating during the last portion of the seek before the write head has reached the target track.
摘要翻译：磁盘驱动器具有位于读/写头附近的电阻加热器作为热飞高高度致动器，并且使用改进的方法来操作飞高致动器。作为该方法的一部分，在寻求磁头接触的风险最小化的过程中，加热器可以被去激活。当接收到写入命令时，在写入初始数据扇区之前，施加一定程度的加热器功率来预加热写入头。该预热加热器功率电平可能高于用于写入的功率电平。然后当写入开始时，较低的功率电平被施加到加热器，使得写头在写入包括初始数据扇区的所有数据扇区期间具有最佳的头盘间隔。即使在寻求期间加热器可以被去激活，在写入头已到达目标轨道之前，控制器可以在寻求的最后部分期间启动预热。

摘要： A magnetic disk drive comprises a recording medium, a slider, and an alignment device for aligning the slider with respect to the medium. No film made of liquid lubricant is disposed on the surface of the medium. The slider incorporates: a slider main body including a thin-film magnetic head element disposed near a medium facing surface; and a protection film made of a tetrahedral amorphous carbon film for protecting the medium facing surface. The alignment device makes the slider retreat from the surface of the medium when the medium is stopped, and makes the slider face toward the surface of the medium when the medium is rotated. The magnetic disk drive further comprises a distance control device for controlling the distance between the medium and the thin-film magnetic head element.

摘要： A thin film magnetic head is provided, in which the amount of protrusion in the periphery of an element portion can be reduced or a local temperature increase of electrode leads of a heating element can be prevented. The thin film magnetic head includes a playback element disposed between lower and upper shield layers, a recording element laminated on the upper shield layer, a heating element which is disposed below a coil layer and which generates heat to allow the playback element to protrude toward the recording medium side through thermal expansion, and a pair of electrode leads including overlapping regions, which are in contact with rear ends of the heating element and which overlap with the upper shield layer, and heat dissipation regions. Furthermore, connection wiring portions of the pair of electrode leads are disposed in a region sandwiched between the upper shield layer and a magnetic layer.
