The present invention relates to a thin-film device including a thin-film element and a lead conductor film. The thin-film element and the lead conductor film are embedded in an insulating film. The lead conductor film has a terminal area at one end thereof, is connected to the thin-film element at the other end thereof, and between the one end and the other end, has an increased surface area portion whose volume is partially occupied by an insulating material to increase surface area. As a result, there is provided a high frequency thin-film device capable of reducing loss and heat generation due to skin effect, particularly a thin-film magnetic head.

The present invention provides a thin film magnetic head capable of satisfying both assurance of recording performance and assurance of reproduction performance. In the case where a lower magnetic layer is formed of an iron cobalt alloy (for example, Fe65Co35) which contains iron in a range of 60 at % to 80 at % and has extremely high saturation magnetic flux density of 2.4 T or higher, a head isolation layer formed of ruthenium (Ru) is provided between the lower magnetic layer and an upper read shield layer portion. As compared with the case where the head isolation layer is not provided between the lower magnetic layer and the upper read shield layer portion, the strength of a recording magnetic field increases and a reproduction output of an MR element is stabilized.

摘要:
A scan trajectory of a laser beam is controlled based on external signals each related to a driving direction and a driving speed, a result obtained by detection of an obstacle, and signals related to distances to the obstacle. For example, at the time of a right turn, a scan trajectory for increasing scan frequency on a portion shifted in a right-turn direction from a center axis in a driving direction is set. At the time of high-speed driving, a scan trajectory for increasing scan frequency on a center portion in the driving direction is set. When the obstacle is detected at a position corresponding to a distance shorter than a threshold distance, a scan trajectory for increasing scan frequency in the vicinity of the obstacle is set. Detection of the obstacle and monitoring of a state thereof are adequately and smoothly performed at the time of changing of the driving direction, the time of high-speed driving, and the time of detection of the obstacle.
