Abstract

액티브패드의 테스트시 손상을 방지하기 위한 수단이 마련된 박막자기헤드(slider)가 개시되어 있다.Disclosed is a thin film magnetic head provided with means for preventing damage during testing of an active pad.

이 개시된 박막자기헤드는 슬라이더(5)와, 외부와 전기적으로 접속되는 복수개의 액티브패드(7)와, 자기기록매체에 정보를 기록하거나 기록된 정보를 검출하는 액티브센서(1)와, 액티브패드(7)와 액티브센서(1) 사이에 위치하며 전기적 신호를 자기적 신호로 자기적 신호를 전기적 신호로 바꾸어주는 코일권선부(3)를 가지며, 각각의 액티브패드(7)와 병렬로 연결되고, 각각의 액티브패드(7)에 따른 재질을 가지는 테스트 전용의 테스트 패드(8)가 더 구비된 것을 특징으로 한다. 이 테스트패드(8)는 바람직하게는 액티브패드(7)에 따른 크기와 형태를 가진다.The disclosed thin film magnetic head includes a slider 5, a plurality of active pads 7 electrically connected to the outside, an active sensor 1 for recording information on a magnetic recording medium or detecting recorded information, and an active pad. It is located between the (7) and the active sensor (1) and has a coil winding (3) for converting an electrical signal into a magnetic signal to a magnetic signal, and connected in parallel with each active pad (7) In addition, a test-only test pad 8 having a material corresponding to each active pad 7 is further provided. This test pad 8 preferably has a size and shape according to the active pad 7.
