There is provided a high-availability duplexing or multiplexing information recorder where a process is not interrupted by a trouble of a drive or a medium. The information recorder is directed to write data instructed to be written from a host system in recording media of at least two drives. The recorder is configured to: detect an abnormality of each drive itself and an abnormality of the recording medium of each drive; cancel the writing of the data in the recording medium of the drive where an abnormality is detected or the drive having the recording medium where an abnormality is detected; and continue the writing of the data in the recording medium of the following drive without notifying any abnormality to the host system, as long as there is at least one drive where any abnormality is not detected and which has the recording medium where any abnormality is not detected.

An internal combustion engine, which has poppet type valve overlap and timing means and has the centerline of each and every cylinder being offset from the rotational axis of the crankshaft in the counter direction of rotation, provides efficient transformation of combustion energy to mechanical rotational power reducing exhaust loss, heat loss and detonation, and increasing volumetric efficiency. The engine also increases effective torque at certain rotational angle of an early stage of a power stroke. Thereby, the invented engine improves thermal efficiency.

A digital demodulator compensates for frequency offset between modulated and unmodulated carrier signals by detecting the frequency offset during a preamble with a known modulation pattern. Samples obtained during the preamble are stored in a memory during clock recovery, and read from the memory after the recovered clock signal has become stable. Phase offset is detected from a histogram of the phase differences between the two carrier signals, calculated modulo a certain phase angle, and compensation for phase offset is applied. The maximum histogram value is found by comparisons made according to a single-elimination tournament plan. In a diversity receiver, the maximum histogram value is used to select the output data.
