Perpendicular magnetic recording disc

A perpendicular magnetic recording medium includes a substrate, a soft magnetic layer, a pre-underlayer, an underlayer, and a main recording layer serving as a magnetic recording layer. The pre-underlayer contains seed crystal grains that serve as a base for crystal grains of the underlayer, and an addition substance that is added between the seed crystal grains and composed of an element having an atomic radius smaller than that of an element forming the seed crystal grains.

When a communication speed of CPUcan be increased, a procedure of automatic phase adjustment involves setting phase shift amount CLK_DLY=n immediately after a vertical synchronization signal interrupt is generated, and reading video detection data VIDEO_DATA(n) after setting phase shift amount CLK_DLY=n+1 when the next vertical synchronization signal interrupt is generated. When CPUis limited in the communication speed, the automatic adjustment is performed by an automatic adjusting circuit which has phase control data memory, video detection data memory, and a trigger input served by vertical synchronization signal S

Automatic adjusting method and circuit

A digital image reproducing apparatus which can easily reproduce image and/or sound recorded by a digital still camera is disclosed. The apparatus has an input interface for inputting image data of the digital still camera. A converter converts the image data into displayable data. The apparatus further has a display for producing a visible image based on the displayable data.
