Abstract
(EN)

When recording information in tracks or in a two-dimensional pattern care must be taken not to irradiate the adjacent tracks or pits. This results in a loss of data density on the recording medium because of the track pitch or pit distance that must be observed. A reduction in track pitch is possible to the point where the focused spot of the laser also irradiates the adjacent land area and tracks or pits. This increases the achievable data density of the recording medium. By using grooves and/or by using a dye with special absorption characteristics the effect of the irradiation of the adjacent tracks or pits can be reduced, effectively only recording marks in the desired location.

(KO) 트랙 혹은 2차원 패턴에 정보를 기록할 때는 인접한 트랙 또는 피트를 조사하지 않도록 주의해야 한다. 이것은 관측되어야 하는 트랙 피치 또는 피트 거리로 인해 기록 매체 상의 데이터 밀도의 손실을 일으킨다. 레이저의 포커스된 스폿이 인접한 랜드 및 트랙 또는 피트를 조사하는 포인트까지 트랙 피치의 감소가 가능하다. 이것은 기록 매체의 달성 가능한 데이터 밀도를 증가시킨다. 그루브를 사용함으로써 및/또는 특별한 흡수 특성을 가진 염료를 사용함으로써 인접한 트랙 또는 피트에 대한 조사 효과가 감소될 수 있어, 소망의 위치에만 마크를 효율적으로 기록할 수 있다.
