5. The data read method as claimed in claim 3, further comprising the step of:
(d) carrying out a read retry process, said step (b) setting the unit to said number of bits when the read retry process is carried out a predetermined number of times.
6. The data read method as claimed in claim 1, wherein said step (b) generates the read data made up of the data values having the highest frequency for each unit when the comparison results are identical at least a predetermined number of times.
7. The data read method as claimed in claim 1, wherein said step (b) increases the number of bits forming the unit when the comparison results are identical at least a predetermined number of times.
8. The data read method as claimed in claim 1, wherein said step (b) decreases the number of bits forming the unit when the comparison results are different at least a predetermined number of times.
9. The data read method as claimed in claim 1, further comprising the step of:
(d) carrying out a read retry process, said step (b) being carried out when the read retry process fails a predetermined number of times.
10. A storage apparatus comprising:
reading means for reading identical data from one region on a recording medium a plurality of times;
generating means for comparing the data read the plurality of times in units of one or a plurality of bits to obtain comparison results, and generating read data made up of data values having a highest frequency for each unit based on the comparison results; and
correcting means for carrying out an error detecting and correcting process with respect to the read data.
11. A storage apparatus comprising:
a reading section reading identical data from one region on a recording medium a plurality of times;
a generating section comparing the data read the plurality of times in units of one or a plurality of bits to obtain comparison results, and generating read data made up of data values having a highest frequency for each unit based on the comparison results; and
an error correcting section carrying out an error detecting and correcting process with respect to the read data.
12. The storage apparatus as claimed in claim 11, wherein said generating section varies a number of bits forming the unit.
13. The storage apparatus as claimed in claim 12, wherein said generating section sets the unit to a number of bits which makes the comparison results identical with a highest frequency.
14. The storage apparatus as claimed in claim 13, wherein said generating section sets the unit to said number of bits at an arbitrary timing.
15. The storage apparatus as claimed in claim 13, further comprising:
a retry section carrying out a read retry process,
said generating section setting the unit to said number of bits when the read retry process is carried out a predetermined number of times.
16. The storage apparatus as claimed in claim 11, wherein said generating section generates the read data made up of the data values having the highest frequency for each unit when the comparison results are identical at least a predetermined number of times.
17. The storage apparatus as claimed in claim 11, wherein said generating section increases the number of bits forming the unit when the comparison results are identical at least a predetermined number of times.
18. The storage apparatus as claimed in claim 11, wherein said generating section decreases the number of bits forming the unit when the comparison results are different at least a predetermined number of times.
19. The storage apparatus as claimed in claim 11, further comprising:
a retry section carrying out a read retry process,
said generating section being carried out when the read retry process fails a predetermined number of times.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An incontinence treatment device comprising:
a non-porous sub-urethral sling;
a first extension member attached to a first end of the sling;
a first anchor attached to the first extension member;
a first line attached to the first end of the sling and inserted through a bore formed through the first anchor, the first line including a stop device fixed to the first line with the first anchor positioned between the stop device and the sling;
a second extension member attached to a second end of the sling;
a second anchor attached to the second extension member, the second anchor including a channel formed through the second anchor and a restrictor segment provided in the channel; and
a second line attached to the second end of the sling and inserted through the channel, the second line including an adjustment device attached to the second line that is movable through the channel formed through the second anchor;
wherein the restrictor segment is configured to resist movement of the adjustment device through the channel.
2. The incontinence treatment device of claim 1, wherein the non-porous sub-urethral sling is a substantially solid film that is adapted to reduce tissue growth onto a surface of the non-porous sub-urethral sling.
3. The incontinence treatment device of claim 1, wherein each of the first and second anchors includes at least one protrusion projecting outward relative to a central axis of the anchor that is configured to engage with tissue.
4. The incontinence treatment device of claim 1, wherein a maximum lateral dimension of the adjustment device is larger than a maximum lateral dimension of the restrictor segment.
5. The incontinence treatment device of claim 1, wherein the channel is formed through the second anchor between opposed ends of the second anchor and the restrictor segment is provided in the channel at an approximate midpoint between the opposed ends of the second anchor.
6. The incontinence treatment device of claim 1, wherein the second anchor has a first end and a second end, the first end disposed nearer to the sub-urethral sling than the second end, and the adjustment device is movable through the channel from the first end to the second end and the restrictor segment is configured to resist movement of the adjustment device from the second end to the first end of the second anchor.
7. The incontinence treatment device of claim 1, wherein the adjustment device is movable through the channel from a first position that locates the adjustment device between the second anchor and the sling to a second position that locates the second anchor between the adjustment device and the sling to thereby tighten the sling by shortening an effective distance of the device between the first and second anchors.
8. The incontinence treatment device of claim 7, wherein the adjustment device is movable through the channel from the second position to the first position to thereby loosen the sling by increasing the effective distance of the device between the first and second anchors.
9. The incontinence treatment device of claim 1, wherein each of the first and second anchors includes at least two tissue engagement wings that configure each anchor for insertion into a membrane covering an obturator foramen of a user.
