The present invention provides a recording head, a recording head adjusting system, and a recording head adjusting method. A recording head includes: a head module having a recording surface; a support member that supports the head module; a first direction position adjusting unit that adjusts the first-direction position of the head module; a rotation direction adjusting unit that adjusts the angular deviation of the rotation direction; and a position detection unit that detects the first-direction position of the head module that is used when performing adjustment by the first direction position adjusting unit and the rotation direction adjusting unit. The rotation direction adjusting unit includes a rotation support mechanism for rotatably supporting the head module within the plane parallel to the recording surface and a second direction moving mechanism for moving the adjustment position of the head module in a second direction perpendicular to the first direction.
