플로피 디스크 구동장치 및 그구동방법Floppy Disk Drive and Driving Method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 플로피 디스크 구동장치의 블록도.1 is a block diagram of a floppy disk drive device according to the present invention.

제2도는 제1도의 작동설명을 위한 플로우 챠트도.2 is a flow chart for explaining the operation of FIG.

Claims (2)

플로피 디스크 구동장치에 있어서, 플로피 디스크를 회전작동시키며 플로피 디스크내의 저장 데이타를 억세스하는 플로피 작동수단(1)으로 부터의 신호를 플로피 디스크의 작동을 제어하기 위한 플로피 디스크작동 제어수단(2)을 경유하여 공급받고, 상기 플로피 디스크 작동수단(1)으로부터의 신호에 따른 인터럽트 수단(8)의 인터럽트 번지내의 명령데이타를 인터럽트 제어수단(7)을 경유해 공급받아 해독하여 상기 플로피 디스크를 작동하기 위한 신호를 상기 플로피 디스크 작동제어수단(2)에 공급하며, 메모리 수단(6)에 저장된 데이타를 공급받아 그 데이타를 판독하도록 구성되는 주제어수단(4)과, 상기 주제어수단(4)에 일정주기의 펄스신호를 공급하도록 구성되는 타이머 수단(3)과, 상기 메모리수단(6)에 일정한 시간데이타를 저장하도록 구성되는 시간데이타 발생수단(5)으로 구성되는 것을 특징으로 하는 플로피 디스크 구동장치.In the floppy disk drive apparatus, a floppy disk drive control means (2) for controlling the operation of the floppy disk via a signal from the floppy operating means (1) for rotating the floppy disk and accessing stored data in the floppy disk. And the command data in the interrupt address of the interrupt means 8 according to the signal from the floppy disk actuating means 1 are supplied via the interrupt control means 7 to decrypt the command data to operate the floppy disk. Is supplied to the floppy disk operation control means (2), the main control means (4) configured to receive data stored in the memory means (6) and read the data; A timer means 3 configured to supply a signal and to store certain time data in the memory means 6 Floppy disk drive, characterized in that consisting of time data generating means (5). 플로피 디스크 구동방법에 있어서, 시작신호로부터 메모리 수단에 선결되어 저장된 시간데이타를 저장하는 단계와, 상기 메모리 수단에 저장된 데이타를 타이머 수단의 펄스신호 출력에 따라 1씩 감소시키고 플로피 디스크를 작동시키는 단계와, 상기 단계로부터 플로피 디스크를 억세스한후 플로피 디스크를 교체하여 억세스하거나 최초의 플로피 디스크를 재억세스 할 경우 상기 메모리 수단에 저장된 데이타를 판독하는 단계와, 상기 단계에서 판독한 데이타값이 “0”인지의 판단하여 플로피 디스크를 재억세스한 다음 상기 메모리 수단에 다시 선결된 시간 데이타 저장하고, 억세스한 데이타를 처리하는 단계와, 판독한 데이타값이 “0”인지의 판단에 따라 최초 플로피디스크를 억세스한 데이타를 처리하고 상기 선결된 시간데이타를 저장하는 단계로 복귀하는 단계로 구성되는 것을 특징으로 하는 플로피 디스크 구동방법.A method of driving a floppy disk, the method comprising: storing time data stored in advance from a start signal to a memory means, decreasing data stored in the memory means by one according to a pulse signal output of a timer means, and operating a floppy disk; Accessing the floppy disk after accessing the floppy disk from the step, and reading the data stored in the memory means when accessing the floppy disk again or accessing the first floppy disk, and whether the data value read in the step is "0". Re-access the floppy disk in accordance with the determination, and store the pre-determined time data in the memory means, process the accessed data, and access the first floppy disk according to whether the read data value is "0". To process the data and store the predetermined time data Floppy disk drive characterized in that consisting of a step of returning to step. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
