摘要： A disc device includes a first traverse chassis holding a first optical pickup unit which performs recording/reproduction of information on a first surface of a disc, a second traverse chassis holding a second optical pickup unit which performs recording/reproduction of information on a second surface of the disc, and first and second biasing members which bias the first and second traverse chassis, respectively, in directions of coming closer to each other. The first and second traverse chassis are coupled to each other so as to turn around a turning axis at a rear side of a housing and extending in a width direction of the housing. At least one of the first and the second biasing members is attached while being inclined with respect to each of a conveying direction of the disc, and a thickness and the width directions of the housing.
