凍りという欠点があった。In conventional optical disk processing devices, in order to prevent data from being duplicated on an irreversible source disk medium, it is necessary to use one piece of software to thoroughly check whether data has been written to a specified sector. 7 Therefore, this original disk processing device is in a low state due to the 1 internal thread command being issued before the printing of the thread command R (-), and the gutter is low. Even though the data was almost 1n in R, the re-instruction order was given to Kanayama, and the data was destroyed.
It had the drawback of freezing.
