Abstract: PURPOSE:To obtain excellent quality of a picture in variable speed reproduction by arranging a normal data area and a search data area on one and the same track. CONSTITUTION:A video signal input is given to a coder 1 for normal reproduction and a coder 2 for searching. The normal reproduction coder 1 compresses image data as required or provides an output of usual reproduction data to a formatter 3 as they are.

Abstract: PURPOSE:To obtain a semiconductor integrated circuit which can be operated at high speed by a method wherein the prescribed number of memory cells are used as one block and a bipolar transistor inside a fundamental cell is used as a driver for driving the block. CONSTITUTION:Fundamental cells 8, 9, 10 and 11 are arranged in an array shape; BiCMOS gate arrays of a type that they are spread on the whole surface are constituted. MOS Trs covering eight memory cells are used as one block. When NMOS Trs and PMOS Trs are not mixed as the memory cells inside one block, the operation of sense amplifiers 6 and 7 is made optimum.

Title: Magneto-resistance effect type magnetic head
Inventor: TAKAGI HITOSHI
IPC: G11B5/39
Filed: 1983-03-17
Abstract: PURPOSE:To constitute a titled head so that a shape demagnetizing field in the track width direction is small even in case when the track width is narrowed, and also the resistance value of a magneto-resistance effect element does not drop, by providing a slit-shaped cut part on a ferromagnetic thin film. CONSTITUTION:A slit-shaped cut part 1a having a width (d), a depth S and an interval W is provided on an MR element 11. A connecting terminal 12 to be connected is provided on both ends of the MR element 11, and a current J is made to flow. The current J scarcely flows to the slit-shaped cut side, therefore, an effective element width to a resistance value is decreased to (w-S) from (w). On the other hand, when the slid width (d) is made sufficiently smaller than a core width l, the influence exerted on a shape demagnetizing field by the slit- shaped cut part can be disregarded. When the element width (w), the slit width (d) and the slit length S are set suitably, it is possible to obtain an MR head having a sufficient reproducing output by a small bias magnetic field.
