SPECIFICATION
Information recording carrier
Background of the invention
Field of the invention
The present invention relates to an information recording carrier in which information is stored in a recording region, and in particularto an information recording carrier in which information comprising a relief pattern is stored in regionsotherthanthe above-described recording region and which can be handled easily even by the blind.
Related background art
It has recently become possible to carry out reproduction of information by using an optical information recording carrier such as an optical file ora compact disc. Furthermore, reproduction of information employing an optical information recording carrier of a card type (referred to as "optical card" hereinafter) which exhibits excellent portability and has a relatively large capacity has recently started to attract attention.
Figure 1 is a typical plan view showing an embodi
ment of the recording format of a conventional optical card and Figure 2 isa partiallyenlargedviewof the same.
In the two drawings, a recording region 2 is prov
ided on an optical card 1 which serves as a recording carrier, the recording region 2 comprising a plurality
of bands 3 arranged therein. Each of the bands 3
comprises a plurality of inforamtion tracks 4 (for ex
ample, 4600 tracks) arranged therein and each ofthe tracks 4 has an information capacity of about several tens to one hundred bits (for example 46 bits). The
information tracks 4 comprise a start bit 20, a stop bit
21, a track numbering region 22, and a data region 23
(including a parity bit). Each of the bands is divided
by reference lines 5 (referred to as " R lines" here
inafter), The optical card 1 is provided with a home
position HP.The arrow A shows the direction in
which the optical card 1 moves during reproduction
and the arrow C shows the direction in which inform
ation read scanning is performed by an optical head
during reproduction. Figure 3 is a schematic block
diagram of an apparatus for reproducing an optical
card having the recording format described above.
In the same drawing, the optical card 1 can recipro
cate in the direction ofthe arrowA by means of a
rotational mechanism 6. The information recorded in
the optical card 1 is read out and reproduced in each
track by an optical head 11. Firstly, lights from a light
source 7 such as a LED are gathered by a lens system
8 and then illuminate the optical card 1. The image
on a track is imaged on a unidimentional sensor
array 10 by an imaging optical system 9. Thus, electr
ical signals corresponding to the information recor
ded on the tracks 4 are output from the sensor array
10. In order to access an intended track on the optical
card 1,the optical head 11 is firstly moved in the dir
ection of the arrow Con the basis of the home posi
tion HP and a band 3 involving the intended track is
then selected by counting the number of R lines
which have been read during this time.Then, the track numbering region 22 of an information track which isto be imaged on the sensor array 10 is reproduced, as the optical card 1 is moved in the direction of the arrow A, and when the number of the intended track is detected, information in the data region 23 of the track detected is reproduced.
However, although an information recording carrier such as an optical card, as described above, has a high recording density and thus a wide range of applications thereof may be considered, there is a problem in that a blind person cannot easily and surely discriminate the contents recorded in the information recording carrier, the head and the tail thereof, and the direction in which the carrier is inserted into a reproducing apparatus.
Summary ofthe invention
The present invention has been achieved in consideration of the disadvantage of the abovementioned information recording carrier and it is an object of the invention to provide an information recording carrier which can be easily handled by the blind.
To achieve the above-described object, an information recording carrier for reproducing information to which the present invention relate, is characterized by being provided with an information portion comprising a convex-concave relief pattern on the surface of the carrier.
In addition, to achieve the above-described object, a certain form of an information recording carrier of the present invention is characterized by comprising a recording region in which a particular item of information is stored and an information recording portion provided in the vicinity of the recording region in which information with respect to the abovedescribed particular information is recorded in the form of a relief pattern.

Detailed description of the preferred embodiment
A particular embodiment of The present invention
is described with reference to the drawings.
Figure 4 is a plan view showing an optical card which is an embodiment of the present invention
and Figure 5 is a partially enlarged view ofthe re
cording format thereof.
In Figure 4, reference number 4denotes an optical card; reference number2, a recording region thereof; reference number3, bands; reference number 4, information tracks; and reference number 5, R lines. They are the same as those in Figure 1, as described above. A plurality of the tracks 4 is continuously collected in the bands 3 so as to compose blocks 15 and a plurality of these blocks is adapted to be arranged in the direction of the arrowAto form the bands 3.
In this embodiment, the first block 1 5a in the top band is used as a directory region. The names of all items of data recorded in the recording region of the optical card 1 ,the length of each item of data, the numberofthe block in which the top item of each data is recorded, and the position of the top item of data in this block are recorded in the directory region. The last track 4a of the directory region 1 5a is employed as a home position mark.On the other hand, the block names are respectively recorded as address information in the top tracks in the remaining blocks otherthan the directory region 1 spa. Reference number 16 denotes an information portion which is formed by a convex-concave relief pattern in a blank space on the side ofthe recording region 2, for example, the title ofthe content recorded in the recording region2 is indicated by raised letters or braille symbols. Furthermore, the marksfordis- criminating the head and the tail ofthe optical card 1 and indicating the insertion\ direction of the optical card 1 are formed by braillS symbols in the informa- tion portion 16.
Figure 5 typically shows the enlarged portions of blocks (N-1), N, and (N +1) in a certain band. In this embodiment, as shown in the drawing, data M isfinished in the middle of a certain track 4 in the block N and data (M +1) immediately commences to be recorded in this track. Therefore, the optical card 1 of this embodiment has no blank space in the recording region, which is thus utilized with maximum efficiency.
An embodiment of a method for reproducing the above-mentioned information recording carrier is described blow. An optical card is considered here as an information recording carrier having the recording format shown in Figures 4 and 5,while the reproducing apparatus shown in Figure 3 is used as an apparatus for reading information from the optical card.
Firstly, the optical head 11 is moved in the direction ofthe arrow C so as to access the band 3 containing the directory region 1 spa. Then, the optical card 1 is moved in the direction of the arrow A so as to read the information recorded in the directory region 1 5a and the home position mark4a. For example, when the data (M + 1 ) is accessed, the optical head 11 is moved in the direction ofthe arrow C and the optical card 1 is moved in the direction of the arrow A on the basis of the information read from the directory region 15a so asto access the top ofthe block N including the data (M+1 ), the optical card 1 then being further moved in the direction ofthe arrow A so asto access the top item of the data (M + 1).This access from the top ofthe block N to the top item of the data (M+ 1) is effected by counting the number of information track scannings by the sensor array orthe number of information bits on the pasis of a clock signal, the top position of the data tom + 1) having been previously read from the directory region.
Thereadingofthedata(M+1) is completed onthe basis of the data-length information obtained from the directory region 15a.
Figure 6 is a block diagram showing an embodiment of an apparatus for reproducing the information recorded in the information recording carrier in accordance with the present invention. The abovementioned operations of reproducing information are described in further detail with reference to this drawing.
The sensor array 10 ofthe optical head 11 is driven by a sensor array driver 30, scans the image in an information trackwhich is imaged on the sensor array 10, and inputs a signal with respect to the image in a binarization circuit 31. The output from the binarization circuit 31 is input in a clock reproducing circuit 32 and the clock signal which is reproduced in the reproducing circuit 32 is output in a demodulation circuit 33 and a counter 34. An information signal is input in the demodulation circuit 33 from the binarization circuit 31 and the tnformation signal input is demodulated in the demodulation circuit on the basis of the clock signal.
When a command to reproduce data is input in a controller 36 from a command input means such as a key board, a driving command is venerated from the controller36 to an optical head denying means 37 and an optical card driving means 38 whereby the optical head 11 accesses the directory region 15a of the optical card 1, and a driving command is generated from the controller 36to the sensor driver 30 whereby the information in the directory region 15a is read out.
Consequently, the information signal of the directory region 15a output from the demodulation circuit 33 is stored in the RAM in the controller 36.
Then, in correspondence with the name of an intended data input from the command input means 35, the optical head driving means 37 and the optical card driving means 36 are driven on the basis ofthe content stored in the RAM 39 so that the access to the top item of the intended data is performed. Atthe same time, a command forthe counter34to count the length of intended data is generated from the controller 36 on the basis of the content stored in the
RAM 39 so that counting is started simultaneously with the start of the reproduction of the intended data. As a result, the information signal with respect to the intended data which has been demodulated in the demodulation circuit 33 is once stored in a buffer memory 40 and the intended data having a suitable length is output by the command generated from the controller 36 on the basis of the resultofthedata- length counting bythe counter34. In this embodiment, since information is read from the optical card 1 in a reciprocating motion and fetching of a signal becomes discontinuous and lacking in continuity, information is output as a continuous signal by using the buffer memory 40.
In the above-described embodiment,the directory region and the home position mark are continuously formed and thus an access operation is efficiently conducted by the optical head.
As described above, since the optical card 1 has a large recording capacity for data information and is capable of rapidly performing an access, it is pos sible for this card to be suitably applied as an optical card forthe blind; for example, information obtained by reading a novel may be recorded in the recording region 2 and the title thereof may be described in the information portion 16 by using braille symbols. It thus becomes unnecessary to take a great deal of time as is normally required in producing a con ventional book comprising braille symbols and deci- phering it, and the blind are thus able to obtain as much information as ordinary people.
Additionally, in the above em bodiment, the information portion 16 is provided on the side ofthe recording region 2, but it is not limited to this and may be provided on the side opposite to the recording region 2, i.e.,the reverse side.
In the information recording carrier shown in Figure4, information is recorded in the information portion 16 by using braille symbols. A recording carrier such as the optical card 1, however, has a certain limit with respect to the area in which a braille symbols pattern may be recorded. Therefore, information indicating the insertion direction of the card 1 and the head and the tail thereof may, for example, be effectively recorded by using a particular pattern such as a relief pattern in an arrow form.
In addition, although the information recording carrier shown in Figure 4 has the information portion 16 formed, for example, along one of the long sides of the optical card 1 the information portion 16 may alternatively be formed across the width of the optical card 1.
Generally, when a blind person reads out information in the information recording portion 16 which is presented on the surface of the information record ing carrier, theyfirstly touch the whole surface ofthe carrier with their fingers to find the information re- cording portion 16 and then read the information recorded in the information recording portion 16. During this time, however, there is a great possibility that dirt, dust, or grease will adhere to the recording region 2 ofthe information recording carrier. Thus, when information is reproduced from the recording region 2 by a particular method, errors occur in reading information and thre is a problem in that the information cannot be reproduced therefrom.
Therefore, in the case of blind users, it is preferably to construct the information recording carrier in such a mannerthatthe users do not touch the recording region 2 as far as possible. An example of the configuration is described hereinafter.
The recording region 2 or a particular region surrounding the recording region 2 is formed at a position below or above other regions. In other words, a difference in level is provided at the boundary between the recording region 2 and the other regions.
By utilizing such a configuration, the blind may find in the information recording portion 16 from the re maining regions other than the recording region 2 using the difference in level as a standard. Thus, the possibility that they will directly touch the whole surface of the recording region 2 is reduced.
Additionally, the circumference of the recording region 2 may be surrounded by a convex or concave relief pattern. In this case, users can easily find the information recording portion 16 from the remaining portions other than this pattern by cofirming this convex or concave relief pattern.
In another configuration, a notch is provided ori the edge ofthe information recording carrier near the portion in which the informatiqn recording portion 16 is formed (the long side on the upper side of the optical card 1 shown in Figure 4). By utilizing this configuration, users can firstly find the notch by touching the edge of the carrier with theirfingers and then the informtion recording portion 16 by touching the portion near the notch so as to read the information.
Ordinarily, an information recording carrier of a card type such as the optical card 1 shown in Figure4 is delivered in the direction of the length ofthe optical card 1 during reproduction of information, but it is put into a reciprocating motion so that information may be read out. A method for moving (driving) the optical card 1 at this time mainly involves a method in which the optical card 1 is mounted on a supporting memberwhich is moved orthe optical card 1 itself is delivered by means of a driving roller.
In either of the above-described method in which the movable supporting member or the driving roller is used, a part ofthesurface ottheoptical card 1 is brought into contact with the memberforfixing the optical card 1 to the supporting memberorwiththe roller. In this case, if the information recording portion 16 comprising a relief pattern is presented in this contact portion, there is a possibility of a problem occurring in that the distance between the head for reproducing information and the optical card 1 may change or it may be impossibleforthe optical card 1 to be supported and moved smoothly.Therefore, when, in particular, the information recording carrier is of a card type such as the optical card 1, it is desirable for the information recording portion 16 to be formed in a portion which is separated from the above-described contact portion.
Furthermore, it is preferable for the convex or concave portion of the relief pattern in the information recording portion 16 to have such a height that blind users can easily read it by touching it with theirfingers and that no trouble is produced during the reproduction of information.
As described above, by providing an information portion comprising a conved or concave relief pattern on the surface of an information recording carrier, the present invention displays the effect of enabling the blind to easilyand surelydiscriminatethe contents recorded in the information recording carrier, the head and the tail thereof, and the direction in which the carrier is inserted into a reproducing apparatus, and to handle it as ordinary people do.
