Title: Conductive wafer carrier
Inventor: MINENAGA NORIAKI
IPC: H01L21/673
Filed: 1990-11-13
Abstract: PURPOSE:To enable smear of a wafer to be reduced by screening an area between a part of a handgrip and a wafer-storage part of a carrier main body with an insulating object. CONSTITUTION:A hand grip 1 is used to carry a carrier 2 and consists of a conductive substance such as metal. Then, a plastic insulating film 4 is provided on an inner surface at a side where the hand grip 1 of the conductive carrier main body 2 is provided. Therefore, when a electrified wafer 3 is stored, an entire carrier is electrified due to induction electrification so that the hand grip 1 which consists of a conductive substance is in an electrified state. Thus, elimination of electricity from the hand grip 1 prevents a foreign material which is adhered to the hand grip 1 from being brought closer to the wafer side as the hand grip 1 and the wafers 3 are separated by the use of insulating films 4.

IPC: G11B5/012
Filed: 1990-11-15
Abstract: PURPOSE:To shorten the latency time by selecting the nearest magnetic head to read by means of a plurality of magnetic heads information recorded in different sectors of a specific cylinder. CONSTITUTION:The same control information is recorded to a specific cylinder by the use of magnetic heads 0-3. The cylinder is divided to 32 sectors with a shift of every 1/4 rotation.

The rotating position is detected by a counter which is cleared by a signal indicative of the index 12 and increased by a signal showing each sector. In this constitution, the average rotating time of the disk before starting read of information becomes 1/8 of one rotation, thus accelerating the processing speed. Therefore, this method is considerably effective when a large number of magnetic heads is present.
