Abstract
Abstract An apparatus and method of recording and reproducing information on a recording medium including recording at least a first track of encloded data information and with the data information occuring at first regular intervals along the recording medium and recording a second track of clock information and with the clock information occurring at second regular intervals along the recording medium and with the second regular intervals occuring no more than every other one of the first regular intervals. The encloded data information on the first track is reproduced and stored and with the reproduction and storage controlled in accordance with the reproduction of the clock information in the second track. The second track of clock information is reproduced by at least a pair of spaced sensors for successively reproducing the clock information along the second track and with the reproduction of the clock information successively alternating between the sensors and wherein the reproduction and storage of the encloded data information is controlled by the successive alternating reproduction by the pair of sensors so that each portion of the encoded data information occurring at the first regular intervals is not reproduced and stored until both sensors have alternately reproduced clock information.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
244 words
An article of manufacture for storing data information and clock information for reproduction by first means which reproduces and stores the data information and by second means, including at least a pair of sensors, coupled to the first means and responsive to the clock information which second means controls the reproduction and storage of the data information by the first means in accordance with the sensing of the clock information to have the data information at one position reproduced by the first means in response to the sensing of particular clock information by a first one of the pair of sensors and to have the same data information at the one position stored by the first means in response to the sensing of the same particular clock information by the second one of the pair of sensors, and with the article of manufacture including, a recording medium for receiving the data information and the clock information, first means forming at least a first track on the recording medium for storing the data information at first predetermined intervals along the first track on the recording medium, and second means forming a second track on the recording medium for storing the clock information at second predetermiNed intervals along the second track on the recording medium and with the second predetermined intervals occurring no more than every other one of the first predetermined intervals and with the second predetermined interval a multiple of the first predetermined interval.
Claim 2
Dependent Claim
244 words
An article of manufacture for storing data information and clock information for reproduction by first means which reproduces and stores the data information and by second means, including at least a pair of sensors, coupled to the first means and responsive to the clock information which second means controls the reproduction and storage of the data information by the first means in accordance with the sensing of the clock information to have the data information at one position reproduced by the first means in response to the sensing of particular clock information by a first one of the pair of sensors and to have the same data information at the one position stored by the first means in response to the sensing of the same particular clock information by the second one of the pair of sensors, and with the article of manufacture including, a recording medium for receiving the data information and the clock information, first means forming at least a first track on the recording medium for storing the data information at first predetermined intervals along the first track on the recording medium, and second means forming a second track on the recording medium for storing the clock information at second predetermiNed intervals along the second track on the recording medium and with the second predetermined intervals occurring no more than every other one of the first predetermined intervals and with the second predetermined interval a multiple of the first predetermined interval.
Claim 3
Dependent Claim
38 words
The article of manufacture of claim 1 wherein the data information and the clock information is stored on the recording medium in the form of first areas having a different transmissivity than second areas of the recording medium.
Claim 4
Dependent Claim
15 words
The article of manufacture of claim 1 wherein the first and second tracks are parallel.
Claim 5
Dependent Claim
27 words
The article of manufacture of claim 1 wherein the data information is stored along a plurality of parallel tracks and with the information stored in binary form.
Claim 6
Dependent Claim
47 words
The article of manufacture of claim 1 wherein the recording medium is a credit card and the data information and the clock information is stored on the card in parallel tracks in the form of first areas of different transmissivity than the remaining area of the card.
Claim 7
Dependent Claim

The article of manufacture of claim 1 wherein the first and second predetermined intervals form discrete positions along the first and second tracks and wherein there is one discrete position representing clock information for two discrete positions representing the data information.
Claim 9
Independent Claim
147 words
A method of storing encoded data information and clock information on a recording medium for reproduction by reproducing and storing the data information and by reproducing the clock information using at least a pair of sensors and with the alternate reproduction of the clock information by the pair of sensors at periodic clock information positions controlling the reproduction and storage of the data information at periodic data information positions, including the following steps: forming at least a first track on the recording medium and storing the encoded data information at first predetermined intervals along the first track on the recording medium, forming a second track on the recording medium and storing the clock information at second predetermined intervals along the second track on the recording medium, and providing the second predetermined intervals at a multiple of and at least every other one of the first predetermined intervals.
Claim 10
Independent Claim
147 words
A method of storing encoded data information and clock information on a recording medium for reproduction by reproducing and storing the data information and by reproducing the clock information using at least a pair of sensors and with the alternate reproduction of the clock information by the pair of sensors at periodic clock information positions controlling the reproduction and storage of the data information at periodic data information positions, including the following steps: forming at least a first track on the recording medium and storing the encoded data information at first predetermined intervals along the first track on the recording medium, forming a second track on the recording medium and storing the clock information at second predetermined intervals along the second track on the recording medium, and providing the second predetermined intervals at a multiple of and at least every other one of the first predetermined intervals.
