Abstract
Abstract In a disk unit containing in a predesignated size, an arm, read/write heads secured to an end of arm, a printed circuit board, and leads connecting read/write heads to the printed circuit board, the disk unit of the present invention is realized by: employing a straight-type arm in place of a conventional dog-leg shaped arm; providing a structure for mounting a printed circuit board on a side of the disk unit where a space is made by employing the straight-type arm; moving a printed circuit board conventionally mounted above the disks to the above-mentioned space, thus evacuating the upper part of the disks; and providing additional disks in the above-mentioned evacuated upper part of the disks to increase storage capacity of a disk unit.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
98 words
A disk unit comprising: a disk having a rotational axis thereof; a read/write head, positioned onto said disk, for reading information out and/or writing information on said disk; an arm, connected to said read/write head, for positioning said read/write head onto a desired position of said disk; a housing having a wall provided in parallel with the rotational axis of said disk, the wall having a depressed portion; and a printed circuit board, connected to said read/write head and located in the depressed portion, said printed circuit board extending in parallel with the rotational axis of said disk.
Claim 2
Dependent Claim
98 words
A disk unit comprising: a disk having a rotational axis thereof; a read/write head, positioned onto said disk, for reading information out and/or writing information on said disk; an arm, connected to said read/write head, for positioning said read/write head onto a desired position of said disk; a housing having a wall provided in parallel with the rotational axis of said disk, the wall having a depressed portion; and a printed circuit board, connected to said read/write head and located in the depressed portion, said printed circuit board extending in parallel with the rotational axis of said disk.
Claim 3
Dependent Claim
47 words
A disk unit according to claim 1, further comprising: a lead connecting said read/write head to said printed circuit board; and diverting means, provided on said arm, for changing a route said lead follows so that said lead is kept away from parts of said disk unit.
Claim 4
Dependent Claim
28 words
A disk unit according to any one of claim 1 or 2, wherein said depressed portion is provided in a space outside an area where said arm swings.
Claim 5
Dependent Claim
16 words
A disk unit according to claim 2, wherein said diverting means is an L-shaped metal fitting.
Claim 6
Dependent Claim
24 words
A disk unit according to claim 1 wherein said printed circuit board mounts circuits which receive and send read/write signals from/to the read/write head.
Claim 7
Dependent Claim
103 words
A disk unit comprising: a plurality of disks having a rotational axis thereof; a plurality of read/write heads, positioned onto said disks, for reading information out and/or writing information on said disks; a straight-type arm connected to said read/write heads, for positioning said read/write heads onto a desired position of said disks; a housing having a wall provided in parallel with the rotational axis of said disks, the wall having a depressed portion; and a printed circuit board, connected to said read/write heads and located in the depressed portion, said printed circuit board extending in parallel with the rotational axis of said disks.
Claim 8
Dependent Claim
103 words
A disk unit comprising: a plurality of disks having a rotational axis thereof; a plurality of read/write heads, positioned onto said disks, for reading information out and/or writing information on said disks; a straight-type arm connected to said read/write heads, for positioning said read/write heads onto a desired position of said disks; a housing having a wall provided in parallel with the rotational axis of said disks, the wall having a depressed portion; and a printed circuit board, connected to said read/write heads and located in the depressed portion, said printed circuit board extending in parallel with the rotational axis of said disks.
Claim 9
Dependent Claim
20 words
A disk unit according to claim 6, wherein said depressed portion is formed inward from the wall of said housing.
Claim 10
Dependent Claim
24 words
A disk unit according to claim 6 wherein said printed circuit board mounts circuits which receive and send read/write signals from/to the read/write head.
