Recording apparatus

A recording apparatus comprising:

• a receiving unit that receives a televised program;
• a recording unit that records the program being received by the receiving unit to an optical disk;
• and
• a commercial message detecting unit that detects a switch from main program to commercial message and a switch from commercial message to main program by detecting a change in an audio mode of an audio signal included in the program being received by the receiving unit and measuring a time period for which the audio mode is constant when the recording unit is recording the program,
• wherein the recording unit:
• sets a chapter break based on a preset first time interval upon the switch from main program to commercial message being detected by the commercial message detecting unit;
• sets the chapter break, based on a second time interval which is longer than the first time interval, upon the switch from commercial message to main program being detected by the commercial message detecting unit;
• and
• records, in a lead-in area of the optical disk, information showing a start position of each chapter that is set based on the first time or the second time;
• wherein the recording apparatus further comprises:
• a playback unit that reads the information recorded in the lead-in area of the optical disk and playbacks the program recorded on the optical disk based on the information;
• and
• an operation unit that receives input for setting the second time interval.
