  • Patent number: 5199090
    Abstract: A magnetooptic head is fabricated on a glass slider and flown adjacent a magnetooptic disk in a disk drive. The transducer is fabricated on an end of the glass slider. A planar or channel waveguide structure, fabricated by ion exchange in the end face of the glass slider, couples light from a light source, such as a laser diode, to the disk for reading or writing. The head employs near-field optical techniques at the operating flying height, eliminating the need for a focusing servo. Near field operation also allows increased bit and track densities due to reduced spot size and direct overwrite using Magnetic Field Modulation on current generations (simple) magnetooptic thin films.

  • Patent number: 4482951
    Abstract: A method for use with a computer which directly transfers incoming data into the computer memory. A functional address contained in a received message is used to index a pointer in a vector table. The indexed pointer addresses an input control block associated with the functional address. The input control block is used to control the flow of data into the computer memory. The input control block also controls access to the computer memory for subsequent messages having the same functional address.
