Recording apparatus and transport method

A transport method that transports a medium by correcting a target transport amount based on a correction value, the transport method comprising:

• storing in advance in a memory a plurality of correction values each associated with a relative position of the head and the medium;
• correcting a target transport amount based on correction values, which are in number according to a size of the target transport amount, and which include the correction value according to the relative position when transporting by the target transport amount;
• and
• transporting the medium based on the target transport amount that has been corrected;
• wherein each correction value is associated with a range of the relative position to be applied with that correction value, and
• the correcting the target transport amount comprises assigning weights to the correction value according to a ratio of a range of the relative position that changes when transporting by the target transport amount to the range of the relative position to be applied with the correction value.

A transport method that transports a medium after correcting a target transport amount based on a correction value, the transport method comprising:

• calculating a plurality of first correction values each associated with a relative position of the head and the medium;
• storing in a memory second correction values each associated with a target transport amount, by calculating the second correction values, with respect to each target transport amount of a plurality of target transport amounts set in advance, based on the first correction values, which are in number according to a size of the target transport amount, and which include the first correction value according to the relative position when transporting by that target transport amount;
• correcting the target transport amount based on the second correction value corresponding to the target transport amount, when transporting by that target transport amount;
• and
• transporting the medium based on the target transport amount that has been corrected;
• wherein each of the first correction values are associated with a range of the relative position to be applied with that first correction value, and
• the correcting the target transport amount comprises assigning weights to the first correction value according to a ratio of a range of the relative position that changes when transporting by the target transport amount and the range of the relative position that is to be applied with the correction value, and calculating the second correction value.

A recording apparatus comprising:

• a head;
• a transport mechanism that transports a medium in a transport direction with respect to the head, according to a target transport amount;
• and
• a controller that controls the transport mechanism based on the target transport amount that has been corrected, after correcting the target transport amount, with second correction values calculated based on first correction values, which are in number according to a size of the target transport amount, and which include the first correction value associated with a relative position of the head and the medium when transporting by the target transport amount;
• wherein each of the first correction values are associated with a range of the relative position to be applied with that first correction value, and
• the controller assigns weights to the first correction value according to a ratio of a range of the relative position that changes when transporting by the target transport amount and the range of the relative position that is to be applied with the correction value, and calculates the second correction value.
