Title: Index pulse generator for data recorder storage device and disk drive
Inventor: JIEFUREI ARAN MIRAA
IPC: G11B27/10
Filed: 1991-02-05
Abstract: PURPOSE: To provide error tolerance in index mark information which read back from the servo face of a magnetic disk pack. CONSTITUTION: A read back circuit 36 converts a raw data signal from a magnetic head 26 on the servo face 34 into a digital pulse. An index mark detection circuit 38 is driven by the output of the read back circuit 36 and the index mark detection circuit 38 gives index pulse output by using an error tolerance index generation method. The increment sequence of a non-zero code, which contains a specified servo index frame and has redundancy in a series of preceding continuous servo data frames, is written. An error tolerant circuit reads and decodes servo frame data and maintains the counting of the encountered non-zero code. When counting reaches the desired count of the non-zero code and the minimum matching number of a non-zero frame counter and actual frame decoding is satisfied, the index pulse is generated.

Abstract: PURPOSE:To connect surely an optical fiber and lens and to reduce the loss of light by deforming the optical fiber elastically in a sleeve and pressing the end face of the optical fiber to the surface of the lens with its elastic restoring force. CONSTITUTION:Before an adhesive 2 is hardened, an end face 4a of an optical fiber bare conductor 4 is polished directly by a polishing material 9. At this time, though a projecting part of the optical fiber bare conductor 4 is pressed into a sleeve 1, the end face 4a is always pressed to the polishing material 9 by its elastic restoring force. After this processing, the sleeve 1 is inserted into a sleeve 7 before the adhesive 2 is hardened, and the end face 4a of the optical fiber bare conductor 4 is pressed to one end face 6a of a lens 6, and an end face 1a of the sleeve 1 is brought into contact with one end face 6a of the lens. In this state, sleeves 1 and 7 are stuck to each other by a solder 8 or the like. Consequently, the optical fiber is brought closely into contact with the surface of the lens completely, and therefore, they are connected with less loss of light.
