Abstract

PURPOSE:To speed up the input/output of data by dividing the data each into record or block unit and to perform the simultaneous input/output actions to the i-th track. CONSTITUTION:In an output (write) mode the output data stored in a data buffer memory 14 is divided for each record by a control part 11 and sent to a data buffer memory 15i set opposite to the tracks where the simultaneously outputted. Then the output actions are carried out simultaneously to the corresponding track. In an input (read) mode the input data is stored in the memory 15i corresponding to the decided tracks where the input actions are carried out simultaneously and then stored in the memory 14 in the order of tracks by the part 11. Then the input data is sent to a CPU 30 from the memory 14 via an input/output channel 31. Thus the input/output of data is speeded up at a high speed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic disk processing device constituting an information processing system, and more particularly to a method for recording data on a magnetic disk device.

[Conventional technology]

Conventionally, the data recording method in the magnetic disk device of this type of magnetic disk processing device is to start from a cylinder, track, and record position specified in advance on the magnetic disk medium, and to switch the track position when the recording area of the track ends. It was done by method.

[Problem that the invention seeks to solve]

The data recording method of the conventional magnetic disk processing device described above has the disadvantage that it becomes an obstacle to speeding up, since the recording operation is continued by switching the track position when the recording area on the track is completed. be.

[Means for solving problems]

The magnetic disk processing device of the present invention records data,
Alternatively, it has means for dividing into blocks and performing input/output operations on the i-th track simultaneously.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows an embodiment of the invention. In Figure 1,
It consists of a magnetic disk processing device 10, a control section 11, a seek address storage section 12, a data length storage section 13, a data buffer storage 14, a data central processing unit 30, and an input/output channel 31.

In FIG. 1, cylinder, track, and record positions are sent from the central processing unit 30 to the magnetic disk processing unit IO via the input/output channel 31 as the starting address of the magnetic disk unit 20 for inputting and outputting data. (hereinafter referred to as the seek address) and the data length are sent. Output (write)
In the case of , the write data is also sent to the seek address storage section 12, data length storage section 13, and in the case of output, respectively.
The data is stored in the data buffer storage 14.

In the control unit 11, the track position of the magnetic disk device 20 is determined based on the seek address from the seek address storage unit 12, and the number of tracks to be simultaneously input and output is determined based on the data length from the data length storage unit 13. is required.

In the case of output (writing), the output data stored in the data buffer memory 14 is divided into record units by the control unit 11, and sent to the data buffer memory 15i corresponding to the track to be output simultaneously. Output operations are simultaneously performed on the tracks that are to be output.

In the case of input (reading), the input data is stored in the data buffer memory 15i corresponding to the determined tracks on which the input operation is performed at the same time, and is stored in the data buffer memory 14 according to the tracks by the control unit 11, It is sent to the central processing unit 30 via the input/output channel 31.

〔Effect of the invention〕

As explained above, the present invention divides input/output data to and from a magnetic disk device into records or blocks, and simultaneously inputs/outputs the divided data to multiple track positions, reducing data input/output time. This has the effect of being able to significantly shorten the time and increase speed.
