The diffraction grating divides return light from the guide layer in accordance with areas. The areas include a first area and a second area that does not overlap the first area. The light-receiving element includes (i) a first detecting cell group which receives a zero-order beam to which astigmatism is imparted, (ii) a second detecting cell group which receives at least one of a positive and negative first-order beam, which passes the first area and made astigmatic, and (iii) a third detecting cell group which receives at least one of a positive and negative first-order beam, which passes the second area and made astigmatic."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Recording/reproducing apparatus","description":"According to an embodiment, a recording/reproducing apparatus includes a diffraction grating and a light-receiving element.
