Patent DE-4028703-A1 (DE)
Inventor: KUEHN HANS-ROBERT
IPC: G11B7/095
Filed: 1990-09-10
Abstract: A process is disclosed for measuring or adjusting the radial and tangential angles of a light beam. In an optic reproduction device, such as a CD player, care must be taken that the data scanning light beam irradiates the disk as normal as possible. Because of the disk warp, however, the radial and tangential angles of the light beam change with each turn of the disk. Because of disk and device tolerances, the optical axis usually deviates from the normal. During reproduction, these deviations change. EP-PS 0 070 070 describes a costly optic measurement device to adjust the radial and tangential angles with respect to a fixed axis. In order to adjust the radial angle O R and the tangential angle O T of incidence of the light beam on the disk without additional measurement devices, the data signal (HF) is demodulated in an amplitude demodulator (DM). The adjustment signal UR = C  * sin  phi  * cos  alpha  for the radial angle OR and the adjustment signal UT = - C * cos  phi  * sin  DOLLAR (a) for the tangential angle OT are derived from the amplitude C and the phase relation  phi  of the demodulated data signal (M). The invention has applications in optic reproduction devices such as CD players, vidéo disk players and DRAW disk players, or in magneto-optic recording and reproduction devices.
