    Notes: A magneto-optical head with circular polarized light incident on a Co/Pt superlattice medium is studied. Differential absorption due to magnetic-circular-dichroism (MCD) is used for erasable data detection. This MCD detection system utilizes an optical isolator to minimize the feedback to the laser. The tradeoff for its reduced complexity is the loss of the common mode noise reduction capability. A disk is tested dynamically with the MCD detection system. With a linear medium velocity of 7.56 m/s and a frequency of 5 MHz a carrier-to-noise ratio of 40 dB is demonstrated.

    Notes: Abstract 650 couples with idiopathic subfertility (mean duration: 5.7 year, range 2–21 years) were treated during 2870 cycles by three assisted conception methods (each involving mild ovarian stimulation): I timed intercourse (TI), II intrauterine insemination (IUI), III in vitro fertilization/embryo transfer (IVF/ET). Treatment started with TI in most cases and then changed to IUI after three to six cycles. Couples who failed to conceive were treated after another 3–9 cycles by IVF/ET. An overall cumulative pregnancy rate of 80.2% was reached after 18 treatment months. The pregnancy rates per treatment cycle were: TI 5.3%, IUI 6.9%, IVF/ET 15.8% (per oocyte retrieval)
