摘要： PROBLEM TO BE SOLVED: To avoid adverse effect such as a crosstalk current to a reproducing head due to high-frequency current of a recording head or turning on/off of a heat generating resistor. SOLUTION: The head gimbal assembly includes: a magnetic head assembly 1 provided with the recording head 1-2, the reproducing head 1-1, and the heat generating resistor 1-3 controlling the fly height of a magnetic head; and a suspension for mounting the magnetic head assembly 1. The wiring HTx, GTx of the heat generating resistor is disposed so that wiring RxX, RxY of the reproducing head is disposed therebetween. The wiring of the heat generating resistor is disposed between the wiring of the recording head and wiring of the reproducing head. A current wave form or a voltage wave form to the heat generating resistor having the wiring disposed near the wiring of the reproducing head is the wave form having a time constant of ≥1 μsec.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic disk unit which is free from the damage and runaway of a magnetic head due to the ruggedness on a surface and lack of a servo signal in a loading/unloading zone.
SOLUTION: The magnetic disk unit equipped with a loading/unloading mechanism for loading/unloading the magnetic head slider 2 to and from a magnetic disk 3 provided with a loading/unloading zone 12 of a prescribed length in a circumferential direction is recorded with a specific command and pattern 14 forward in the circumferential direction of the loading/unloading zone of the magnetic disk. When a controller reads out the recorded specific command, the controller moves the magnetic head slider to a track on an inner peripheral side so as to evade the loading/unloading zone. In reading/writing the data of the track existing within the same radius as the radius of the loading/unloading zone, the controller returns the magnetic head slider again to the above track.

摘要翻译：要解决的问题：提供一种磁盘单元，其由于表面上的坚固性和装载/卸载区域中的伺服信号不足而没有磁头的损坏和失控。
解决方案：记录有装载/卸载机构的磁盘装置，用于将磁头滑块2装载到设置有沿周向的规定长度的装载/卸载区12的磁盘3上特定的指令和图案14在磁盘的装载/卸载区域的圆周方向上向前。当控制器读出记录的特定命令时，控制器将磁头滑动器移动到内周侧的轨道，以便避开加载/卸载区域。在读取/写入与加载/卸载区域的半径相同的半径内存在的轨道的数据时，控制器将磁头滑块再次返回到上述轨道。版权所有（C）2005，JPO＆NCIPI
