Abstract
Abstract A receiver/recorder of television transmissions is disclosed which operates automatically on a stand-by basis to record continuously television transmissions from at least one channel onto a reusable large capacity recording medium such as a magnetooptic disk. The recording is accomplished without user intervention and the system includes an indexing for distinguishing a recent recording from an older recording which is partially overlapped by the recent recording.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
185 words
An apparatus for receiving and recording television transmissions, comprising: means for continuously recording television transmissions from at least one channel onto a random-access rewritable recording medium wherein said means for recording provides for a continuous recording of received television transmission; means for reproducing said recorded television transmission; means for detecting a complete filling of said recording medium and providing a first signal fed to a return means to return a recording head to the beginning of said medium in order to rewrite subsequent transmissions at the beginning of said medium while simultaneously erasing transmissions which were previously recorded and providing a complete filling indication signal; means for periodically writing to said medium a code representing a filling of said medium wherein said code remains the same until a specified filling is completed and wherein said code is changed to a second value when the recording head is returned to the beginning of the medium; indexing means responsive to said code wherein said indexing means is recorded on said medium for automatically distinguishing a first in time recorded transmission from a second in time recorded transmission.
Claim 2
Independent Claim
185 words
An apparatus for receiving and recording television transmissions, comprising: means for continuously recording television transmissions from at least one channel onto a random-access rewritable recording medium wherein said means for recording provides for a continuous recording of received television transmission; means for reproducing said recorded television transmission; means for detecting a complete filling of said recording medium and providing a first signal fed to a return means to return a recording head to the beginning of said medium in order to rewrite subsequent transmissions at the beginning of said medium while simultaneously erasing transmissions which were previously recorded and providing a complete filling indication signal; means for periodically writing to said medium a code representing a filling of said medium wherein said code remains the same until a specified filling is completed and wherein said code is changed to a second value when the recording head is returned to the beginning of the medium; indexing means responsive to said code wherein said indexing means is recorded on said medium for automatically distinguishing a first in time recorded transmission from a second in time recorded transmission.
Claim 3
Dependent Claim
42 words
The apparatus according to claim 1 further comprising a means for detecting said code and a means which, after an interruption, provides for continuation of recording following the last location containing said second code value found at the beginning of the medium.
Claim 4
Dependent Claim
41 words
The apparatus according to claim 1 further comprising a backup energy source and a means for detecting an interruption in a supply current and means, supplied by said backup energy source, for writing a code indicating where the recording has stopped.
Claim 5
Dependent Claim
15 words
The apparatus according to claim 1 including a recording head and a separate reading head.
Claim 6
Dependent Claim
19 words
The apparatus according to claim 1 comprising a means of control for simultaneously recording at least two television channels.
Claim 7
Dependent Claim
15 words
The apparatus according to claim 1 wherein said recording medium comprises at least one disk.
Claim 8
Dependent Claim
15 words
The apparatus according to claim 5 wherein said recording medium comprises at least two disks.
Claim 9
Dependent Claim
20 words
The apparatus according to claim 1 further including a clock for continuously recording date information simultaneous with said television transmissions.
Claim 10
Dependent Claim
17 words
The apparatus according to claim 8 further comprising a means of fast searching from said date information.
Claim 11
Dependent Claim
19 words
The apparatus according to claim 8 including a means for preventing erasure of preselected transmissions between two predetermined dates.
Claim 12
Dependent Claim
37 words
The apparatus according to claim 1 further comprising a means for detecting the presence of television transmissions and an element responsive to said means for detecting the presence of television transmissions to control recording of said transmissions.
Claim 13
Dependent Claim
28 words
The apparatus according to claim 11 wherein said means for detecting the presence of television transmissions includes a means for detecting the presence of absence of line-frequency signals.
Claim 14
Dependent Claim
13 words
The apparatus according to claim 1 wherein said code is a binary code.
Claim 15
Independent Claim
81 words
The apparatus for recording data comprising: means for continuously recording said data onto a random access rewritable recording medium wherein said means for recording provides for continuous recording of received data; means for periodically writing to said medium a code representing a filling of said medium wherein said code remains the same until a specified filling is completed and wherein said code is automatically changed to a second value when the recording head is returned to the beginning of the medium.
Claim 16
Independent Claim
81 words
The apparatus for recording data comprising: means for continuously recording said data onto a random access rewritable recording medium wherein said means for recording provides for continuous recording of received data; means for periodically writing to said medium a code representing a filling of said medium wherein said code remains the same until a specified filling is completed and wherein said code is automatically changed to a second value when the recording head is returned to the beginning of the medium.
Claim 17
Dependent Claim
42 words
The apparatus according to claim 14 further comprising a means for detecting said code and a means which, after an interruption, provides for continuation of recording following the last location containing said second code value found at the beginning of said medium.
