Title: Signal recording/reproducing device and signal recording /reproducing method
Inventor: TSUTSUI KEIICHI
IPC: G11B11/10
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To desirably reproduce a signal recorded in high density by making the diameter vertical to a recording track of a optical spot at the time of reproducing smaller than that at the time of recording. SOLUTION: A laser beam for reproducing or a laser beam for recording emitted from a semiconductor laser 2 is made incident to a collimetor lens 3, is made to be parallel luminous flux by the collimeter lens 3 and is made incident to a LCD panel 4. The LCD panel 4 is a spot shape changing-over means which changes over the size of the diameter vertical to the recording track of the optical spot on a magneto-optical disk 100 through the beam shaping of the laser beam. At the time of reproducing, the drive of the LCD panel 4 is controlled, the size of the diameter of the optical spot is changed over and, thereby, the reading of information signals, that is, the detection of movement of domain walls is performed by the optical spot having a diameter in a track transverse direction which is made to be smaller than that in the track transverse direction of the optical spot at the time of recording.
