摘要： A thin-film magnetic head provided with at least one MR read head element includes a lower shield layer, an upper shield layer, and an MR layer formed between the lower shield layer and the upper shield layer. A profile of the upper shield layer, appeared at an ABS, has obtuse or rounded upper corners at end edges of the upper shield layer along a track-width direction.

摘要： Timely and proper flying height adjustment is achieved using a controller, which is designed for a magnetic recording and reproducing apparatus that does not use a magnetic head having a heating element for flying height adjustment without any modification. A head amplifier includes a write amplifier for applying a write current to a write head element, a read amplifier for amplifying a read voltage output from a read head element and outputting a read signal, a heating element driver for applying a heat generating current to at least one heating element for adjusting a flying height, and a heat controller for controlling the heating element driver.
摘要翻译：使用控制器实现及时和适当的飞行高度调节，所述控制器被设计用于不使用具有用于飞行高度调节的加热元件的磁头的磁记录和再现装置，而不进行任何修改。头放大器包括用于向写头元件施加写入电流的写入放大器，用于放大从读取头元件输出的读取电压并输出读取信号的读取放大器，用于向发生电流施加发热电流的加热元件驱动器用于调节飞行高度的至少一个加热元件和用于控制加热元件驱动器的热控制器。
