摘要： In a magnetic tunnel effect type magnetic head 20 having a magnetic tunnel junction element 26 sandwiched with conductive gap layers 25 and 27 between a pair of magnetic shielding layers 24 and 28, the conductive gap layers 25 and 27 are formed from at least one nonmagnetic metal layer containing a metal element selected from Ta, Ti, Cr, W, Mo, V, Nb and Zr. Therefore, the magnetic head 20 can have an improved face opposite to a magnetic recording medium.

摘要： A head substrate and a protective substrate are formed of an electrostatic-discharge resistant conductive material having an electrical resistivity of 102 to 1010 Ωcm. These substrates are electrically connected to a base metal through the use of conductive paste and are set to a ground potential via the base metal and a rotating drum. This suppresses a discharge current flowing through an MR element when an electrostatically charged substance touches or approaches a magnetic reproducing head, a terminal, a conducting wire, etc. to generate an electrostatic discharge. The magnetic reproducing head including an MR element and the like is prevented against an electrostatic discharge damage. It is possible to provide the magnetic reproducing head, a head drum apparatus, and a magnetic recording-reproducing apparatus which can highly effectively prevent an electrostatic discharge damage.
摘要翻译：头基板和保护基板由电阻率为10〜10Ω·cm的静电电阻导电材料形成。这些基板通过使用导电膏电连接到基体金属，并且通过基底金属和旋转鼓被设置为接地电位。当静电充电物质接触或接近磁性再现头，端子，导线等产生静电放电时，这抑制流过MR元件的放电电流。包括MR元件等的磁性再现头被防止静电放电损坏。可以提供可以高度有效地防止静电放电损坏的磁性再现头，磁头鼓装置和磁记录重放装置。
