Abstract
Abstract A digital audio tape recorder and a method for operating the same, especially in a music program jump selecting mode. In one embodiment, the state of an erasure-preventing tab is detected, and TOC (Table-Of-Contents) information is transferred from the tape to a TOC information memory only when the erasure-preventing tab is set to an indicate an unrecordable state. In accordance with another embodiment, when the music program number of the music selection presently being reproduced is known and the program number is aligned, a target music program number is calculated and displayed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
A digital audio tape recorder of a rotary head type, comprising: erasure-preventing tab detecting means for detecting open and closed states of an erasure-preventing tab on a cassette loaded into said recorder; TOC information memory means for storing TOC information read from a magnetic tape; and TOC information memory control means for controlling transfer of said TOC information in said TOC information memory means in response to a detection result produced by said erasure-preventing tab detecting means, whereby said TOC information is transferred to said TOC information a memory means when said erasure-preventing tab of said cassette is set to an unrecordable state, and said TOC information is not transferred to said TOC information memory means when said erasure-preventing tab is set to a recordable state.
Claim 2
Dependent Claim
126 words
A digital audio tape recorder of a rotary head type, comprising: erasure-preventing tab detecting means for detecting open and closed states of an erasure-preventing tab on a cassette loaded into said recorder; TOC information memory means for storing TOC information read from a magnetic tape; and TOC information memory control means for controlling transfer of said TOC information in said TOC information memory means in response to a detection result produced by said erasure-preventing tab detecting means, whereby said TOC information is transferred to said TOC information a memory means when said erasure-preventing tab of said cassette is set to an unrecordable state, and said TOC information is not transferred to said TOC information memory means when said erasure-preventing tab is set to a recordable state.
Claim 3
Independent Claim
85 words
A method for operating a digital audio tape recorder, comprising the steps of: detecting a state of an erasure-preventing tab on a tape cassette loaded into said recorder; controlling transfer of TOC information from a tape a contained in said tape cassette to a TOC information memory in response to a detection result produced by said detecting step, whereby said TOC information is transferred to said s memory only in the case said erasure-preventing tab is set to a state indicating said cassette is unrecordable.
Claim 4
Independent Claim
85 words
A method for operating a digital audio tape recorder, comprising the steps of: detecting a state of an erasure-preventing tab on a tape cassette loaded into said recorder; controlling transfer of TOC information from a tape a contained in said tape cassette to a TOC information memory in response to a detection result produced by said detecting step, whereby said TOC information is transferred to said s memory only in the case said erasure-preventing tab is set to a state indicating said cassette is unrecordable.
Claim 5
Independent Claim
157 words
A method for operating digital audio tape recorder, comprising the steps of: loading a cassette containing a magnetic tape into said recorder; a driving said cassette in a running search mode to search for a program first recorded on said tape; stopping said search when predetermined subcode data is detected; judging whether TOC information is written in a subcode o region of said first-recorded program; if no TOC information is found in said subcode region, commencing a normal reproducing mode and interrupting reading of TOC information; if TOC information is found in said subcode region, detecting a state of an erasure-preventing tab on said cassette; and controlling transfer of TOC information from said tape to a TOC information memory in response to a detection s result produced by said detecting step, whereby said TOC information is transferred to said memory only in the case said erasure-preventing tab is set to a state indicating said cassette is unrecordable.
Claim 6
Independent Claim
157 words
