Abstract
A recording apparatus includes: a driving unit that drives the transporting unit; a phase detecting unit that detects a phase origin of the transport roller rotating in accordance with the driving of the driving unit and a rotational phase indicating an amount of rotation from the phase origin; a recording unit that performs recording on the sheet transported with the transporting unit; and a control unit that controls the driving unit such that the transport roller rotates within a certain transport range based on a preliminarily set reference phase, forms a first pattern by controlling the recording unit at a first rotation phase at a control start point of the driving unit, forms a second pattern by controlling the recording unit at a second rotation phase at a control end point of the driving unit, and then forms a correction pattern including the first and second patterns.
