Abstract
Abstract A series scene indication is magnetically recorded adjacent appropriate frames in a strip of film by an autowind camera whenever it is in rapidfire mode. The camera includes a magnetic head positioned to record data in a magnetic layer of the film strip as the strip is transported by a take-up reel, and a processor which intelligently senses when the camera is in a rapidfire mode and instructs recording electronics to energize the magnetic head in order to record the series scene indication on the film strip.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
146 words
In a camera which exposes film having a magnetic layer in the film, a shutter controlling the film exposure, an auto wind motor and take-up reel to automatically reposition the film with respect to the shutter and a shutter release button governing a synchronization circuit actuating both the shutter and the auto wind motor, the improvement comprising: a magnetic head positioned to record data on the film as it is transported by said take-up reel, and a processor which senses whether said shutter button is operated such that said synchronization circuit is in a rapidfire mode wherein said auto wind motor and shutter are operated in a rapid alternating sequence, said processor including means for transmitting to said magnetic head a series scene indication code for recording in or near corresponding frames in said film in response to said synchronization circuit being in said rapidfire mode.
Claim 2
Dependent Claim
146 words

Claim 3
Dependent Claim
42 words
The improvement of claim 1 wherein said processor determines whether said synchronization circuit is in said rapidfire mode by sensing whether said shutter button is continuously on during successive actuations by said synchronization circuit of said shutter and said auto wind motor.
Claim 4
Dependent Claim
36 words
The improvement of claim 1 wherein said magnetic head records said series scene indication in a longitudinal magnetic track adjacent the corresponding frame in said film in a direction parallel to the length of said film.
