| 英文摘要 | In a magnetic recording device, a semiconductor laser (LD) is disposed at a position with a predetermined distance from a swing arm having a slider. The laser beam output from the LD is irradiated, via a beam converter and a mirror, to a spherical aberration lens that generates spherical aberration. The laser beam transmitted through the spherical aberration lens is directed to a light incident opening of the slider at a constant angle (perpendicularly), and then to a position of a recording medium at which information is recorded, thereby performing thermal assist at the magnetic recording time. |
