Abstract: 본 발명은 심야전기를 이용한 침대에 관한 것이다. 
     종래의 전기히터가 장치된 침대는 전기요금이 고가한 일반전기를 사용하도록 하였기 때문에 경제적 과부담이 있을뿐만 아니라 심야의 경우는 전력수요가 감소함에 따라 생기는 잉여 전력을 그대로 방전하게 되므로 이는 귀중한 국가적 에너지의 낭비현상을 초래하고 있었던 것이다. 
     본 발명은 이상의 문제점을 해결하고자 발명한 것으로 이의 발명 요지는 침대몸체(1)의 저면에는 단열판(4)이 부착되고 상면에는 세라믹코팅판(3)이 부착되며 그 내부에는 축열매체(6)를 장입하되 이 축열매체(6)의 상부층(6')에는 심야전기와 연결된 히터(5)를 장치하므로서 심야전기 공급시간에는 심야전기로 히터(5)를 가열하고 이때 가열된 축열매체(6)는 상부층(6')에서 하부층으로 점차 축열하게 되고 심야전기를 사용할수 없을때는 즉, 히터(5)의 가열이 없을때는 하부층에 저장된 열이 점차 상승하면서 몸체(1)의 표면 온도를 장시간 유지하도록 하였기 때문에 경제적일 뿐만아니라 심야때 방전하고 있는 국가적 에너지 자원의 재활용에도 크게 기여할수 있는 것이다.

Abstract: PURPOSE: A method for processing a defect area of an optical recording medium is provided to perform a normal replaying in the defect area, depending on whether an error is corrected, or to jump up to other track during the defect area to perform the normal replaying, so as to efficiently process a defect and to stably perform a servo. CONSTITUTION: If a defect is generated(303) during a normal replaying(301), a focus servo holds a tracking servo in a turned-on state and records a defect start position(303). The focus servo maintains a tracking servo state until an RF signal is normally detected, after turning off the tracking servo. If the RF signal is normally detected(304), the focus servo turns on the tracking servo and records an end position of a defect area(305). The focus servo decides whether a position of the turned-on tracking servo is an original track in a normal state(306). If the position is an outer track(307), the focus servo moves to an inner track of the original track by a backward jumping(308), and performs a normal replaying until the focus servo meets the defect area(309,310). If the focus servo meets the defect area, the focus servo decides whether data of the defect area is capable of performing an error correction(311). If not, the focus servo performs a backward jumping to the inner track(312), and performs a normal replaying during length of the defect area(313). The focus servo performs a forward jumping to the original track(314) and replays the original track(315).
