Abstract

The invention provides a writing control device and an image forming device. The write control device includes: a storage unit with N HDDs, where N is an integer greater than 2; a data division unit that divides the data to be written into the storage unit into N unequal divided data; and The write control unit distributes and saves the N pieces of divided data to the N HDDs through parallel operations, wherein the write control unit stores the N pieces of divided data with a data volume larger than that of the first divided data. The second divided data is written in the outer peripheral track than the first divided data.

Description

technical field [0001] The present invention relates to a writing control device and an image forming device for storing data in a distributed manner in a plurality of HDDs. Background technique [0002] Conventionally, in image forming apparatuses, HDDs (Hard Disk Drives) have been used as media for storing large-capacity data such as image data. In the HDD, a disk for data storage is placed in a housing, and the disk is rotated to make the head trace a specific sector to read and write data. [0003] When writing data, data is often written sequentially from the outer peripheral track to the inner peripheral track on the disk (disc). Figure 7 A case is shown in which data is sequentially written to one HDD from the outer peripheral track to the inner peripheral track. The amount of data processed by the HDD differs between the outer peripheral portion and the inner peripheral portion of the disk in one rotation, and the data transfer speed becomes slower (lower in perfor...
