摘要： An image processing apparatus which is set to receive data in the RGB format cannot directly receive image data in the YMCK format although a print process is finally done in the YMCK format.In this embodiment, when RGB data is input from a host computer, renderers respectively render the R, G, and B data, the rendered R, G, and B data are converted into YMCK data by a color space converter, and the YMCK data is output to an engine. On the other hand, when YMCK data is input, renderers respectively render Y, M, C, and K image data, and directly output them to the engine.

摘要： An information recording disk includes detection regions used to confirm presence or absence of written signals, read/write regions available for signal writing and write-project regions which reject signal writing. Regions where the detection regions and read/write regions overlap each other are originally provided with discriminating signals to distinguish these regions from at least the other regions. The write protect regions are distinguished from the read/write regions, referring to information detected by a head assembly.

摘要： A method of re-correcting the position of a head is used in a disk driving device including a zero track restoring arrangement for electrically detecting the zero track position on a magnetic disk, and including a track counter indicating the track position of the magnetic head. The method is configured to monitor the track number of the track counter and never fails to effect re-correction of the position of the head when the track number is "0" or "1".

摘要： A disk driving device includes a rotatably driven information recording disk having multiple recording surfaces. At least two recording surfaces among them are provided with mutually related regions originally assigned with identical signals and mutually related regions originally assigned with different signals. These signals are detected by a head assembly and subsequently compared to each other to specify a region in which the head assembly is located.

摘要： If Y, M, C, and K color component images are serially generated by one color component image generating device in four steps, it takes much time to perform image processing for printing a one-page full-color image. This makes it impossible to increase the printing speed. In addition, since conversion to Y, M, C, and K data is performed before rendering, rendering logic cannot be faithfully implemented, resulting in poor color reproducibility. In order to solve these problems, image generating devices (103–105) respectively render R, G, and B color component images in bitmap memories 106 to 108, which are divided into areas in units of predetermined bands obtained by dividing a page, on the basis of a display list which is common to R, G, and B data and stored in a memory (102). The rendered color component images on a band basis are converted into C, M, Y, and K color component images by a color space converter (109) in synchronism with the operation of a printer engine.
摘要翻译：如果通过四个步骤由一个颜色分量图像生成装置串行地生成Y，M，C和K颜色分量图像，则执行用于打印单页全色图像的图像处理花费大量时间。这使得不可能提高打印速度。此外，由于在渲染之前进行到Y，M，C和K数据的转换，不能忠实地执行渲染逻辑，导致差的颜色再现性。为了解决这些问题，图像产生装置（103-105）分别将位图存储器106至108中的R，G和B颜色分量图像分割成分割为通过划分页面而获得的预定频带的单位的区域 R，G和B数据共同的并存储在存储器（102）中的显示列表的基础。与打印机引擎的操作同步地，通过颜色空间转换器（109）将基于频带的渲染的颜色分量图像转换成C，M，Y和K颜色分量图像。

摘要： A magnetic disk drive device includes a rotatable disk. The disk has at least data tracks and guard band tracks. The data is previously recorded on the data tracks in the reversed magnetization form, whereas no data is recorded on the guard band track. While the magnetic head seeks the data from the tracks, the data is detected at first from the data track. This position where the first data is detected is recognized as a zero track. The magnetic head data seeking is performed based upon this zero track which is electronically detectable.
