a cassette type detection means for detecting said first cassette or said second cassette;

a first writing prohibition detection means for detecting whether to permit to record data in the first format on said recording medium accommodated in said first cassette or said second cassette;

a second writing prohibition detection means for detecting whether to record data in the second format on said recording medium accommodated in said first cassette or second cassette;

a control means; and

a data recording means,

wherein said control means discriminates whether a cassette set in the recording apparatus is said first cassette or said second cassette from a detection signal of said cassette type detection means, performs data recording on said recording medium in the first format via said data recording means in the case where a detection signal of said first writing prohibition means permits to write data on said recording medium when said first cassette is set, and performs data recording on said recording medium in the second format via said data recording means in the case where a detection signal of said second writing prohibition means permits to write data on said recording medium when said second cassette is set,

wherein said first cassette and said second cassette comprise a first hole for indicating whether said first writing prohibition detection means permits to record data in said first format on said recording medium,

wherein said first writing prohibition detection means has a switch having a first pin able to be inserted to said first hole and outputs an on or off detection signal in accordance with whether said first pin is inserted to said first hole,

wherein said first hole is closed when indicating permission of recording data in said first format on said recording medium, so that said first pin of said first writing prohibition detection means is prohibited to be inserted to said first hole,

wherein said first hole is open when indicating prohibition of recording data in said first format on said recording medium, so that said first pin of said first writing prohibition detection means is permitted to be inserted to said first hole,

wherein said cassette type detection means and said second writing prohibition detection means are first and second light reception elements arranged by leaving a predetermined space,

wherein a light emission element for emitting a light able to be received by said first and second light reception elements is further provided,

wherein said second cassette is formed a light incident hole for receiving an incident light from said light emission element and first and second emission holes formed at positions corresponding to said two light reception elements,

wherein said second cassette comprises a deflection means for deflecting a light introduced from said light emission element to said light incident hole in the direction of said two light reception elements and a moving means for deflecting the light introduced from said light emission element to said light incident hole in the direction of one of said two light reception elements by moving the deflection means,

wherein said first cassette does not have said emission hole and produced to be opaque, and

wherein said control means identifies that a second cassette is set in the recording apparatus when either of said first and second light reception elements receives a light, and performs data recording in the second format on said recording medium via said data recording means when said first light receiving element detects light reception.
