Claim 6

A photo compact disk reader, comprising: a data reader reading photographic data from a photo compact disk, the disk having a data recording surface on one side for recording photographs; an orientation reader reading a user markable surface of the compact disk on an opposite side to said data recording surface the markable surface having manually marked and machine readable frame regions providing visual orientation information indicating visual orientation of the photographs by 180° and ±90°; and a photographic orientation and display device orienting and displaying the photographs responsive to the visual orientation information.

Claim 7

A reader as recited in claim 4, wherein said frame regions on said user markable surface comprise manual blanking marks marking whether the photographs should be blanked and said orientation and display device displays responsive to said manual blanking marks.

Claim 8

A reader as recited in claim 4, further comprising a description region on said user markable surface for manually writing a subject matter of the photographs.

Claim 9

A reader as recited in claim 4, wherein the frame regions are arranged in circumferential tracks and said orientation and display device reading the circumferential tracks.

Claim 10

A reader as recited in claim 4, wherein each of the frame regions comprises first through fourth marking areas, the first marking area for indicating photograph blanking, the third marking area for indicating the 180° photograph visual rotation and the second and fourth marking areas for indicating the ±90° photograph visual rotation, respectively.

Claim 11

A reader as recited in claim 8, further comprising a timing track on said user markable surface having timing marks aligned with the first, second/fourth and third marking areas said orientation and display device using the timing track to time reading of the frame regions.

Claim 12

A photo compact disk reader, comprising: a photographic data reader reading a photo compact disk having a data recording side recording photographs optically in photograph tracks; an orientation reader reading the photo compact disk having a markable surface on a side of the photo compact disk opposite said data recording side, said surface having manually marked and machine readable marks, being divided into circumferential tracks including a clock track having timing marks for timing reading of the manually marked and machine readable marks and an orientation track for reading orientation of the photographs from the manually marked and machine readable marks, said orientation track being divided into frame regions corresponding to the photograph tracks, each of the frame regions being divided into orientation quadrants aligned with said timing marks, each orientation quadrant having said markable surface manually marked with machine readable orientation information indicating one of a specific visual orientation of 180° and ±90° and blanking for one of the photographs; an orientation reading device reading the orientation information and orienting the photographs responsive to the orientation information; and a display displaying the oriented photographs.

Claim 13

A photo compact disk reader, comprising: a photographic data reader reading a photo compact disk having a data recording side recording photographs optically in photograph tracks; an orientation reader reading the photo compact disk having a markable surface on a side of the photo compact disk opposite said data recording side, said surface having manually marked and machine readable marks, being divided into circumferential tracks including a clock track having timing marks for timing reading of the manually marked and machine readable marks and an orientation track for reading orientation of the photographs from the manually marked and machine readable marks, said orientation track being divided into frame regions corresponding to the photograph tracks, each of the frame regions being divided into orientation quadrants aligned with said timing marks, each orientation quadrant having said markable surface manually marked with machine readable orientation information indicating one of a specific visual orientation of 180° and ±90° and blanking for one of the photographs; an orientation reading device reading the orientation information and orienting the photographs responsive to the orientation information; and a display displaying the oriented photographs.

Claim 16

An apparatus as recited in claim 11, wherein said orientation reading means comprises at least two light emitting and detector pairs scanning a same surface as the disk rotates and reading the manually marked orientation information; and said data orientation means comprises a processor connected to said pairs, determining photographic orientation from the orientation information, retrieving the photographic data and orienting the photographic data responsive to the orientation information.

Claim 17

An apparatus as recited in claim 12, wherein said disk comprises plural orientation information tracks and said orientation reading means further comprises a multiplexer, connected between said detectors and said processor, for controlling sampling the tracks.

Claim 20

A method as recited in claim 14, wherein step (a) comprises the steps of: (i) rotating the photo compact disk and reading the manually made marks in frame regions arranged in circumferential tracks; and (ii) determining the orientation information from positions of the user marks.

Claim 21

A method as recited in claim 15, wherein step (i) includes reading the manually made marks in synchronism with machines made and readable timing marks on a timing track.
