| 英文摘要 | PURPOSE:To obtain a spot-shaped array laser adapted to be gradually cooled by so disposing at least one of light emitting units that the long axis of a far field pattern aligns in the same line as the long or short axis of a far field pattern of other light emitting unit. CONSTITUTION:An erasure laser chip 1 as an erasure light emitting unit is bonded obliquely at 90 deg. with respect to a conventional one toward a deep step of a heat sink plate 3a, and a recording/reproducing laser chip 2 is bonded in the same direction as a conventional one toward a shallow step. The depth of the step is suitably so designed that the light emitting points of the chips 1 and 2 are aligned on the same line and the long axis direction of the far field pattern of the chip 1 and the short axis direction of the far field pattern of the chip 2 are aligned on the same line. Accordingly, the long axis direction of the erasure radiating beam light becomes parallel to a track direction, and a recording material can be gradually cooled by the long axis radiating beam. |
