Data Coding errors for use with Protective Tape for exploration by the helical rotating Heads made of reed Solomon Code in a First mode ShovelBra along each track grabaciu00f3ndefi nest in first and second Code Words cu00f3digoreed Salomon defined in second Code words.The first and second Reed Solomon codes form a code Word format cadasegunda Product Code has the unasecuenc symbols through a Plurality of adjacent tracksS.The symbols of a single second word decu00f3digo have substantially Uniform displacement between adjacent two symbols in a direction parallel to the course of the film,And also in a perpendicular direction along the tape. Each Second code word extends substantially Along these tracks associated to grab.
