Recording apparatus and recording method

A recording method using a recording apparatus, the recording apparatus comprising:

• a medium supporting part configured to support a medium;
• a recording unit configured to perform recording on the medium;
• a movement unit configured to relatively move with respect to the medium supporting part along a first axis;
• a detection unit attached to the movement unit;
• and
• a control unit, wherein
• the detection unit includes:
• an arm part turnably coupled to the movement unit,
• a contact part fixed at one end of the arm part, and
• a displacement detection unit configured to detect contact and non-contact of the contact part and the medium,
• the contact part is disposed to overlap the medium supporting part in a second axis orthogonal to the first axis,
• the medium supporting part is configured to relatively move along a third axis orthogonal to the first axis and the second axis with respect to the movement unit,
• the arm part turns about a turning shaft when the contact part makes contact with the medium while the movement unit moves,
• the displacement detection unit detects the contact and the non-contact based on a turn of the arm part,
• the control unit causes the displacement detection unit to perform primary detection and secondary detection subsequent to the primary detection,
• in the primary detection, the displacement detection unit detects the contact and the non-contact while moving the contact part in a first direction along the first axis such that when the contact is detected, a movement in the first direction is interrupted, and that the movement in the first direction is restarted after the medium supporting part is separated from the movement unit by a first distance along the third axis, and
• in the secondary detection, the displacement detection unit detects the contact and the non-contact while moving the contact part in a second direction opposite to the first direction such that when the contact is detected, a movement in the second direction is interrupted, and that the movement in the second direction is restarted after the medium supporting part is separated from the movement unit along the third axis until the non-contact is detected.
