摘要： A thermally-assisted magnetic recording head is provided, in which the light-source output can be adjusted according to its variation by environmental influences and over time. The head comprises: a light source; a write head element provided in a element-integration surface; an optical system provided in the element-integration surface and configured to guide a light emitted from the light source to the vicinity of one end of the write head element; and a light detector for monitoring the light-source output, provided in the element-integration surface and comprising a light-receiving surface covering an area directly above at least a portion of the optical system. This light detector with such a light-receiving surface can detect a leakage light emitted from the optical system as a monitoring light. Therefore, feedback adjustment of the light-source output can be realized to stabilize the intensity of light for thermal-assist applied to a magnetic recording medium.

摘要： A method for manufacturing a thermally-assisted magnetic recording head is provided, in which joined are: a light source unit that includes a light source having a surface including a light-emission center on the joining surface side of a unit substrate; and a slider that includes an optical system having a light-receiving end surface reaching a back surface opposite to the opposed-to-medium surface. This method utilizes “semi-active alignment” that uses an alignment light, and comprises steps of: causing a light to enter the light source from a surface opposite to the light-emission center; detecting the light that has passed through the light source and is emitted from the light-emission center to align the light-emission center with the light-receiving end surface of the slider; and bonding the light source unit to the slider. This manufacturing method can achieve the alignment with a sufficiently high alignment accuracy in a short processing time.

摘要： Provided is a light source unit that is to be joined to a slider to form a thermally-assisted magnetic recording head. The light source unit comprises: a unit substrate having a source-installation surface; a light source provided in the source-installation surface and emitting thermal-assist light; and a photodetector bonded to a rear joining surface of the unit substrate in such a manner that a rear light-emission center of the light source is covered with a light-receiving surface of the photodetector. The photodetector can be sufficiently close to the light source; thus, constant feedback adjustment with high efficiency for the light output of the light source can be performed. This adjustment enables light output from the light source to be controlled in response to changes in light output due to surroundings and to changes with time to stabilize the intensity of light with which a magnetic recording medium is irradiated.

摘要： Provided is a thermally-assisted magnetic recording head in which a slider including an optical system is joined with a light source unit. The light source unit comprises: a unit substrate including a joining surface joined with the slider and a source-installation surface adjacent to the joining surface; a light source provided in the source-installation surface and emits light for thermal assist; and a photodetector section formed inside the unit substrate, a light-receiving portion of the photodetector section for receiving light emitted from a rear light-emission center being located on the source-installation surface side. The light source unit includes the photodetector section that enables constant monitoring of light output from the light source. Accordingly, feedback adjustment of the light output can be accomplished. Further, since the rear light-emission center and the light-receiving portion can be located sufficiently close to each other, the light output can be monitored with a higher efficiency.

The HGA comprises a suspension comprising: a base; a first wiring member for the light source and the photodetector, provided on a side of one surface of the base; and a second wiring member for the magnetic head element, provided on the same surface side. The first and second wiring members protrude from the base toward the head to be fixed. As a result, the end portions (connection pads) of the first and second wiring members can be located close to electrodes for light-source and photodetector and electrodes for magnetic head element, respectively. This arrangement enables the end portions of the first and second wiring members to be reliably electrically connected to the electrodes by SBB.
