Abstract:
A rotary magnetic head apparatus comprising:an apparatus body having a stationary drum and a rotary drum rotatively mounted with reference to this stationary drum; and a reproducing magnetic head mounted at said rotary drum side of said apparatus body; wherein said reproducing magnetic head is a magnetoresistive effect magnetic head in which an inter-shield gap is formed between joint surfaces for a pair of guard materials through the intermediation of a pair of magnetic shield thin films, and a magnetoresistive effect element is provided in this inter-shield gap, a groove is formed lengthwise at both width-direction ends of a sliding surface opposite to a magnetic recording medium, said grooves restrict a contact width of said reproducing magnetic head against said magnetic recording medium, and a width of said pair of magnetic shield thin films is larger than a width of said magnetoresistive effect element and is smaller than said contact width.
