Способ записи информации, при котором на оптическом носителе на поликарбонатной основе для однократной записи записывают информацию в виде питов путем воздействия на регистрирующую среду промодулированным лучом сфокусированного лазерного излучения, одновременно кодируя ее помехоустойчивым кодом, отличающийся тем, что избыточность помехоустойчивого кода выбирают с учетом предполагаемого срока хранения носителя по формуле
y ≥ А • 0,897 • ln(3,049+t),
где А - начальная избыточность помехоустойчивого кода, определяемая стандартом записи на оптический диск;
t - предполагаемое время хранения в годах.A method of recording information in which information in the form of pits is recorded on a polycarbonate-based optical medium for one-time recording by exposing the recording medium to a modulated beam of focused laser radiation, while encoding it with a noise-resistant code, characterized in that the redundancy of the noise-resistant code is selected taking into account the expected storage period carrier according to the formula
y ≥ A • 0.897 • ln (3.049 + t),
where A is the initial redundancy of the error-correcting code, determined by the standard of recording on an optical disk;
t is the estimated storage time in years.
