In addition, since data is processed within the disk storage device, it can be easily connected to a host cPU or the like.

Example Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of the present invention.

In FIG. 1, numeral 1 denotes a disk storage medium in which information such as data is stored. 10, 11, and 12 are recording and reproducing heads used to read and write information from the disk storage medium 1. 20 is a head drive mechanism that drives the head 10. Similarly, 2
1 is a head drive mechanism that drives the head 11, and 22 is a head drive mechanism that drives the head 12, respectively. 30 is a signal demodulator that converts the output signal from the head 10 into a digital signal.

Similarly, 31 is a signal demodulator that converts the output signal from the head mechanism 11, and 32 converts the output signal from the head mechanism 12. Reference numeral 40 denotes a data processing unit that has both a data processing function of data processing the output signal of the signal demodulator 30 and a function of controlling the head drive mechanism 20. Similarly, 41
42 is a data processing unit that data-processes the output signal of the signal demodulator 31 and controls the head drive mechanism 21; 42 is a data processing unit that data-processes the output signal of the signal demodulator 32 and controls the head drive mechanism 22; It is. Reference numeral 70 is an interface unit connecting the data processing unit 40.41.42 and the host CPU, which receives an operation command from the CPU to the disk storage device, determines the allocation of the operation of the data processing unit 40.41.42, and notifies it. , a data input/output function between the host cPU and the data processing section 40.41.42, and a function of notifying the host CPU of the status of the data processing section 40.41.42 and the interface section 70.

In the disk storage device configured as described above, there are a group of the head 10, the head drive mechanism 20, the signal demodulator 30, and the data processing section 40, the head 11, the head drive mechanism 21, the signal demodulator 31, and the data processing section 41. group, the head 12, the head drive mechanism 22, and the signal demodulator 32.
The group of data processing units 42 and 42 can each independently move the head position, read data from and write data from the disk storage medium 1, and process the read data. Therefore, if the three groups properly share data processing, data processing speed three times as high as that of a conventional disk storage device having only one data processing section can be obtained. In addition, three data processing units 40
．． 41 and 42 are connected to the host CPU through one interface section 70, so the connection with the host cPU is not particularly complicated.

FIG. 2 is a block diagram showing a second embodiment of the present invention.

In FIG. 2, 1 is a disk storage medium in which information such as data is stored. 10, 11, and 12 are recording and reproducing heads used to read and write information from the disk storage medium 1. 23 is a head drive mechanism that drives the heads 10, 11, and 12. 30 is a signal demodulator that converts the output signal from the head 10 into a digital signal. Similarly, 31 is a signal demodulator that converts the output signal from the head mechanism 11, and 32 converts the output signal from the head mechanism 12. 50 is a data processing unit having a data processing function of data processing the output signal of the signal demodulator 30.

A function to determine and notify the assignment, a function to notify the head position control unit 60 of a head position control command from the host CPU, a data input/output function between the host CPU and the data processing unit 50.51.52, It has a function of notifying the host CPU of the status of the data processing section 50, 51, 52, head position control section, and interface section 71, etc.

The major difference between the first and second embodiments is that the first embodiment has a plurality of head drive mechanisms, whereas the second embodiment has only one head drive mechanism. Therefore, the second embodiment has a simpler structure. Functionally, the first embodiment allows all heads and data processing groups to access and process data anywhere on the disk storage medium. However, in the second embodiment, while the position of a certain head is determined and data is being accessed, other heads can only access positions determined by the relative positions between the heads. In this way, the second embodiment is comparable to the first embodiment in cases where the location of the disk storage medium for storing data can be determined for faster processing, or when the time required for data processing is longer than the access time. Data processing speed is obtained.

Although the present embodiment shows a case where there are three heads and three data processing sections, it is possible to configure the number of heads and data processing sections with any number of two or more, if necessary.

As described in detail, according to the present invention, data stored in a disk storage medium can be processed at high speed, and in addition, post-CP
Since it is easy to connect with U etc., its practical value is great.
