A writing apparatus includes a storage unit configured to store writing data, an acquiring unit configured to acquire pattern information on a plurality of patterns defined in the writing data, based on the writing data, a first table generating unit configured to generate a first table in which each pattern information corresponds to a number of times of using the each pattern information, based on acquired pattern information, for each predetermined region, a Huffman tree generating unit configured to generate a Huffman tree, based on the first table, a second table generating unit configured to generate a second table in which the each pattern information corresponds to a variable length binary code generated by encoding the each pattern information in such a manner that the larger the number of times of using the each pattern information is, the smaller a value of the variable length binary code is, based on the Huffman tree, a converting unit configured to convert data, which is defined by the writing data, in the predetermined region into a predetermined format using the variable length binary code, based on the second table, and a writing unit configured to write the plurality of patterns defined, onto a target workpiece, based on converted data in the predetermined region.
