A recording device includes: a recording and reproducing unit that records or reproduces data stored on a recording medium; and a control unit that interrupts recording during recording performed by the recording and reproducing unit, acquires an evaluation value of a recording quality of a recorded portion, changes recording speed based on the evaluation value, and resuming the recording. The interface includes a first contact interface system for receiving a male connector. The decreased spot size, in combination with an increased angular spread, allows an existing metrology system to measure parameters of a sample, such as a semiconductor or microelectronic device, with improved resolution and without expensive andor complex changes to the mechanics of the metrology system. In embodiments, the context is attached to items in the call history when the voice communication is initiated. A footrest is movable between a retracted position and an extended position. The second storage unit stores the meta-information of the edited target electronic document and a feature value of the meta-information of the edited target electronic document in association with each other.
