  • Publication number: 20180272749
    Abstract: An information processing device is connected to a first reading device to read a recording medium to generate first data, a writing device to write on the recording medium based on second data, and a second reading device to read the recording medium to generate third data. The information processing device includes a first retrieval unit to obtain the first data; an identifying unit to identify the recording medium based on the first data; a second retrieval unit to obtain, upon detecting that the writing device writes on the recording medium, the third data; a determination unit to determine whether the second data differs from the third data; a calculation unit to calculate a number of times of writing on the recording medium; a storage unit to store the calculation value; and an evaluation unit to evaluate the recording medium based on the calculation value.

  • Publication number: 20180239565
    Abstract: A data generating device is for generating writing data. The data generating device is connected to a writing device for writing a character on a recording medium based on the writing data. The data generating device includes an input unit configured to input the character and a layout, the layout being defined by a position, a size, and a range of writing the character; a calculation unit configured to calculate, in response to detecting that the character or the layout is changed, a writing time for writing by the writing device based on whether the character is to be written, an order of writing the character, and the layout; and an output unit configured to generate the writing data based on the character and the layout, and configured to output the generated writing data to the writing device.
