Abstract
Embodiments of the invention provide a compact thin-film magnetic head capable of being increased in the number of terminals, and a magnetic disk drive that uses the thin-film magnetic head. In one embodiment, a thin-film magnetic head is constructed that has a magnetic response element, multiple connection object terminals, multiple lead conductors electrically connected to the magnetic response element, and multiple connection sections each formed between each of the connection object terminals and one of the multiple lead conductors in order to electrically connect each of the connection object terminals and one of the lead conductor. All of the multiple lead conductors are provided in the state where they extend from the magnetic response element to the lower layers of the multiple connection object terminals. A magnetic disk drive using the thin-film magnetic head is constructed.
