Title: Two-laser optical head
Inventor: MIZUNO SADAO
IPC: G11B7/135
Filed: 1986-05-21
Abstract: PURPOSE:To prevent a light beam of a wavelength lambda2 from being made incident in a photodetector by giving a prescribed angle of the light axis of the light beam of wavelength lambda2 leaked from a wavelength selection filter and the light beam of wavelength lambda1 reflected in a disk. CONSTITUTION:A light beam 10a of wavelength lambda1 from the 1st semiconductor laser 10 is transmitted through a polarized beam splitter film face B of a prism 23 to form a light spot 25 on the disk 5. On the other hand, the reflected light of the spot 25 is reflected in the film face B, transmitted through a wavelength selection filter 16 and made incident in the photodetector 31. Then the light beam 20a of wavelength lambda2 from the 2nd semiconductor laser 20 is reflected in the film face B of the filter 16 to form an elliptic light spot 26 on the disk 5. In this case, part of the beam 20a incident in the filter 16 is transmitted through the filter 16. Since an emitted angle theta2 of the transmitted beam 20a is placed at the opposite direction to the beam 10a transmitted through the filter 16, both the beams transmitted therethrough have deviated light axis at an angle of 2theta2, then the leaked beam 20a does not reach the photodetector 31.

IPC: G11B5/60
Filed: 1989-05-09
Abstract: PURPOSE:To deviate a resonance point in the side of a magnetic head assembly over a wide range without fail by providing a notch in a direction crossing a center line in an insulating tube to be fixed to a spring arm in a floating type magnetic head. CONSTITUTION:An insulating tube 15, to which a lead wire 14 is inserted, is fixed to a spring arm 2. In this tube 15, a notch 18 is provided in the direction crossing a center line (c). By providing this notch 18, the flexibility of the tube 15 is increased and the tube 15 can be softly deformed. Thus, a vibration condi tion in the side of the magnetic head assembly is different from that of the magnetic head, for which the notch 18 is not provided, and the resonance point is deviated. Further, since the resonance point in the side of the magnetic head assembly can be widely deviated, even in case the resonance point in the side of a device is slightly moved, the resonance point can be coincident between the magnetic head assembly and device. Then, a core slider 6 is not brought into contact with the magnetic disk. According to the number of the notches 18 or the shape of the notch, the resonance point can be freely deviated.
