摘要:
An optical pickup includes: a light source that emits first light; an objective lens that condenses the first light and allows it to irradiate a track having formed therein a recording mark for intercepting the first light in a uniform recording layer of an optical information recording medium; and a light receiving section that receives transmitted light which has transmitted through the track.
