Abstract

A disk information display device capable of displaying display data responding to the operation of operating part in a complete and in real time, the disk information display device includes: a disk information acquiring unit for acquiring information recorded on a disk; an operating part for making a request to display display data recorded on the disk in response to an operation; a control part that acquires display data responding to a final display request among display requests made during a period, in which display data responding to a former display request is acquired from the disk information acquiring unit, from the disk information acquiring unit when display requests are made in succession by the operation of operating part; and a display that displays the display data acquired by the control part after the display data responding to the former display request is displayed.

Claims

1. A disk information display device comprising:

a disk information acquiring unit for acquiring information recorded on a disk;

an operating part for making a request to display display data recorded on the disk in response to an operation;

a control part that acquires display data from the disk information acquiring unit responding to a final display request among display requests made during a period, in which display data responding to a former display request is acquired from the disk information acquiring unit, when display requests are made in succession by operation of the operating part; and

a display that displays the display data acquired by the control part after the display data responding to the former display request is displayed.

2. The disk information display device as claimed in claim 1, wherein the control part includes a display request signal storing part and a general control part, the display request signal storing part accumulating the number of display requests made by operation of the operating part as the number of display request counts and transmitting the number of display request counts accumulated to the general control part in response to a checking request from the general control part, the general control part transmitting the checking request to the display request signal storing part and transmitting a display data acquiring request to make a request to acquire display data later than display data responding to a former display request by the number of display request counts to the disk information acquiring unit if the number of display request counts transmitted from the display request signal storing part in response to the checking request is one or more and transmitting data transmitted from the disk information acquiring unit in response to the display data acquiring request to the display.

3. The disk information display device as claimed in claim 1, wherein the display data is constructed of a plurality of data that represent a plurality of items.
