Abstract
Abstract In an information recording and/or reproducing apparatus in which a spindle motor rotates a magnetic recording disc at a predetermined speed while a transducer head is in contacting relation to the disc for recording and/or reproducing information signals in substantially circular concentric record tracks thereon, and a transducer positioning device is coupled to the transducer head for positioning the latter on a selected one of said record tracks; a memory is provided for storing identification signals which correspond to the various types of information signals recorded in concentric record tracks, respectively, and a display is coupled to the identification signal storing memory for displaying simultaneously the identification signals for all of the record tracks.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
184 words
Apparatus for recording and/or reproducing different types of information signals in respective concentric circular record tracks on a magnetic recording disc, and which different types of information signals include at least field recorded still image information contained in a respective one of said record tracks and frame recorded still image information contained in a respective pair of said record tracks which are adjacent each other on said disc, comprising: spindle motor means for rotating the magnetic recording disc at a predetermined speed; transducer means for contacting said magnetic recording disc when recording and/or reproducing said information signals in said respective record tracks; transducer positioning means coupled to said transducer means for selectively positioning said transducer means in respect to said record tracks; identification signal storing means for storing identification signals respectively identifying different types of information signals recorded in said respective record tracks; and display means coupled to said identification signal storing means for displaying simultaneously all of said identification signals identifying the types of information signals along with identifications of said respective record tracks in which said types of information signals are recorded.
Claim 2
Dependent Claim
184 words
Apparatus for recording and/or reproducing different types of information signals in respective concentric circular record tracks on a magnetic recording disc, and which different types of information signals include at least field recorded still image information contained in a respective one of said record tracks and frame recorded still image information contained in a respective pair of said record tracks which are adjacent each other on said disc, comprising: spindle motor means for rotating the magnetic recording disc at a predetermined speed; transducer means for contacting said magnetic recording disc when recording and/or reproducing said information signals in said respective record tracks; transducer positioning means coupled to said transducer means for selectively positioning said transducer means in respect to said record tracks; identification signal storing means for storing identification signals respectively identifying different types of information signals recorded in said respective record tracks; and display means coupled to said identification signal storing means for displaying simultaneously all of said identification signals identifying the types of information signals along with identifications of said respective record tracks in which said types of information signals are recorded.
Claim 3
Dependent Claim
44 words
Apparatus as in claim 1; wherein said display means is a cathode ray tube display which functions to display said identification signals in the form of an identification table and which also displays said still image information when reproduced from the respective record tracks.
Claim 4
Dependent Claim
56 words
Apparatus as in claim 1; wherein said signals further include recorded audio information and recorded digital data recorded in respective ones of said record tracks, and said identification signals distinguish between said respective record tracks having said audio information and said digital data recorded therein and said record tracks having said still image information recorded therein.
Claim 5
Dependent Claim
120 words
Apparatus as in claim 3; in which said transducer means includes first and second heads spaced apart in a radial direction of said disc so as to scan adjacent record tracks on the latter; and in which only said first head is made operative when recording or reproducing said field recorded still image information, said audio information and said digital data in said respective ones of the record tracks and, when recording or reproducing frame recorded still image information in said respective pair of adjacent record tracks, said first head is made operative during one revolution of said disc and, without operation of said transducer positioning means, said second head is made operative during the next revolution of said disc.
Claim 6
Dependent Claim
68 words
Apparatus as in claim 1; further comprising control button means actuable to establish program sequences for said transducer positioning means, sequence memory means for storing sequence data corresponding to said program sequences established by said control button means, and program control means coupled to said sequence memory means for controlling said transducer positioning means in sequence in accordance with said sequence data stored in said sequence memory means.
Claim 7
Dependent Claim
39 words
Apparatus as in claim 5; wherein said program control means is operative to interrupt a program sequence and to recover a previous program step of said program sequence in response to operation of one of said control button means.
Claim 8
Dependent Claim
39 words
Apparatus as in claim 5; wherein said control button means includes at least ten keys and a serial track selection key, and said sequence data has mixed therein a random track selection sequence and a serial track selection sequence.
Claim 9
Dependent Claim
34 words
Apparatus as in claim 7; wherein said serial track selection sequence is defined by actuation of said serial track selection key after selection of a start track by selective actuation of said ten keys.
Claim 10
Dependent Claim
163 words
Information recording and/or reproducing apparatus comprising: spindle motor means for rotating a magnetic recording disc at a predetermined speed; transducer means for contacting said magnetic recording disc when recording and/or reproducing information signals in concentric circular record tracks on the discs; transducer positioning means coupled to said transducer means for positioning said transducer means on a selected one of said record tracks on the magnetic recording disc; control button means actuable to establish program sequences for said transducer positioning means; sequence memory means for storing sequence data corresponding to said program sequences established by said control button means; and program control means coupled to said sequence memory means for normally controlling said transducer positioning means in sequence in accordance with said sequence data stored in said sequence memory means, said program control means being selectively operative to interrupt a program sequence and to recover a previous program step of said program sequence in response to operation of one of said control button means.
Claim 11
Dependent Claim
163 words
