A recording device that improves the stability of an operation of recording data in a recording medium is provided. Recording device includes mounting unit, protective cover, open/close detecting unit, buffer, and recording controller. The recording controller performs a control of storing data into the buffer, reading, from the buffer, the data stored in the buffer, and recording the data into the recording medium. When the open/close detecting unit detects that the protective cover is opened, the recording controller performs a control of continuing the operation of storing data into the buffer, and yet stopping the operation of reading, from the buffer, the data stored in the buffer and recording the data into the recording medium.
