摘要： A disk recording and reproducing apparatus using two light beams has a disk driving section for loading a disk-shaped record medium having recording tracks and for rotating the disk-shaped record medium, an optical system having a light beam generating source, a light beam splitting device for splitting a light beam to provide at least a main beam and a sub beam, an optical path forming device for respectively causing the main beam and the sub beam to become incident on two adjacent recording tracks in the disk-shaped record medium loaded on the disk driving section and a photo-detecting device for detecting the condition that at least the sub beam from the disk-shaped record medium loaded on the disk driving section is affected by the recording track. Also provided is a disk rotation control section for controlling the disk driving section such that a relative moving speed of the recording track relative to the main beam incident on the recording track becomes constant, a recording operation section causing the information to be recorded on the recording track on which the main beam becomes incident, and a reproducing operation section for generating a read-out information signal based on a detected output of the sub beam from the photo-detecting device. The resultant read-out information signal is written in a memory at a rate corresponding to the read-out information signal and the read-out information signal written in the memory is read out again at a predetermined reading rate to generate a reproduced information output.

摘要： In a sampled data transmitting apparatus in which the sampled data to be transmitted are divided into odd-numbered samples and even-numbered samples and arranged in different rows of a two-dimensional data array, and in which error correction codes are annexed to each row and to each column of the two-dimensional data array, the row arraying sequence in one of the odd-numbered or even-numbered rows is caused to differ from the row arraying sequence in the other of the odd-numbered or even-numbered rows so that odd-numbered data and even-numbered data continuous with the odd-numbered data are not arranged in one row. In this manner, even when error correction becomes impossible by the error correcting code for one row, interpolation remains feasible because there exist no odd-numbered data or even-numbered data contiguous to each other in the row.

摘要： A droplet ejecting apparatus includes a recording head including nozzles, liquid chambers communicating with the respective nozzles and storing ink, and actuators for applying pressure to the respective liquid chambers; and a print control unit configured to generate drive signals for driving the respective actuators to eject droplets from the nozzles. The drive signal includes a first contracting waveform component for ejecting a droplet and a second contracting waveform component for further contracting the liquid chamber after application of the first contracting waveform component but not ejecting a droplet. The second contracting waveform component is output at oscillation-damping timing at which a pressure wave generated by the first contracting waveform component is damped, in a condition where an environmental temperature is high, and is output at resonating timing at which resonance with the generated pressure wave occurs, in a condition where the environmental temperature is low.

The separate chambers are communicated with the nozzles. The inlet portions are communicated with the corresponding separate chambers. Liquid is supplied from the common chamber to the separate chambers through the inlet portions. The filter unit is disposed between the inlet portions and the common chamber to filter liquid in an area across the separate chambers in a first direction in which the nozzles are arrayed. The ribs are disposed in the filter unit at intervals corresponding in size to at least two of the separate chambers in the first direction to partition the filter unit. The inlet portions are communicated in the first direction with each other in at least one portion of each of the inlet portions facing the filter unit.
