Abstract: A focus adjustment system for an optical disk apparatus has a monitor detector that detects the power of a light beam (4) emitted from a laser (2), and a peak detector (18) produces a peak-detect signal when peak beam power is detected. An optical system (6) directs the light beam through an objective lens (8) onto a disk (10), and feeds light reflected from the disk back to the laser. A focus-error detector (20) receives light reflected from the disk and produces a focus-error signal representing the distance between the objective lens and the disk. A sample-and-hold circuit (22) samples the focus-error signal when a peak-detect signal is produced, and outputs the sampled focus-error signal as a reference signal. A focus controller (24) is operable to move the objective lens toward or away from the disk according to the difference between the focus-error signal and the reference signal.

Abstract: The invention relates to a method for the digital bidirectional data transmission in an optical fibre. Light pulses of the same frequency are used both for the forward and reverse direction of the data transmission. The pulses to be transmitted are reduced to a width Tr from an original width Tb, the mark/space ratio Tr/(Tb - Tr) having to be less than one. The second transmitting/receiving unit must only transmit during a receive pause (Tb - Tr). To achieve an optimum distribution of the optical pulses on the optical fibre 3, the first transmitting/receiving unit 1 measures the timing on the optical fibre 3 and, if necessary, causes the second transmitting/receiving unit 2 to change its transmitting time of its optical signals by means of a modify signal. This produces a control loop which automatically achieves an optimum pulse distribution on the optical fibre within certain limits. <IMAGE>
