Inventor: AWANO HIROYUKI
IPC: G11B11/105
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a magneto-optical head capable of reproducing a ultra high densely recorded fine magnetic domain with high resolution and high sensitivity. SOLUTION: A floating type magneto-optical head 100 is provided with a solid immersion lens 10 and a magnetic coil 4 on a slider 2. A magnetic domain magnify-reproduced film 61 is formed on the bottom surface of the lens 10. At the time of reproducing information, evanescent beams are exuded from the bottom surface of the lens to heat the fine area of the reproduced film 61 to deteriorate coercive force. The magnetic domain 55a of a recording layer is transferred to the heated fine area of the film 61 by leaked magnetic field from the magnetic domain 55a of a recording layer 55 existing under the head 100. A magnified magnetic domain is formed on the film 61 at the time of applying an external magnetic field of the same polarity as the magnetic domain of the recording layer by the coil 4.  Thus, it is possible to distinguish the fine magnetic domain of the recording layer from another fine magnetic domain and to amplify the intensity of a reproduced signal to reproduced it.

Title: Non-volatile semiconductor memory
Inventor: NAKAMURA HIROSHI
IPC: G11C16/02
Filed: 1995-04-28
Abstract: PURPOSE: To shorten a data rewriting time by making a selected block a erasing non-selection state, when operation of data erasing is fully performed. CONSTITUTION: A controller 6 is connected to one part of system wirings in normal system control lines 11 system address/data wirings 10, and an EEPROM chip array. A flash EEPROM memory is divided into plural blocks, memory cells in the same block perform data erasing simultaneously by data erasing operation of the controller 6. The controller 6 specifies erasing selection block address in the EEPROM chip, applies a erasing pulse, and performs multi-block erasing operation. Successively, the controller 6 selects an erasing selection block, and confirms whether this block is in a sufficiently erased state or not. If it is in a sufficiently erased state as a result of confirming, it is made an erasing non-selection block, a data rewriting time is shortened by repeating erasing sequence until all blocks are made erasing non-selection.
