A heat dissipating device includes a heat sink (10), a heat pipe (20), a heat reservoir (30) thermally connecting with the heat sink through the heat pipe, and a fan (40) generating an airflow through the heat sink. The heat pipe includes an evaporating portion (202) attached to the heat sink and a condensing portion (204) attached to the heat reservoir. The heat reservoir is made of metal containing working medium, such as water, therein. The heat reservoir stores or releases heat based on the amount of heat generated by the CPU to realize a compensation to the increase or decrease of temperature of the CPU, whereby the change rate of the temperature of the CPU from idle to busy condition and vice versa can be more stable.

A head including a write element for writing data to a magnetic media, and methods for its production are provided. A write element of the invention includes one or more of a recessed first pole, a heat sink layer, and a shortened yoke length. A method of the invention provides forming an anti-reflective layer before forming a mask layer. During photolithography the anti-reflective layer suppresses undesirable reflections off of features, such as vertical sidewalls, that otherwise limit how closely to such features portions of the mask layer can be formed.
